age to travel alone on plane

Kids on planes: What you should know before booking a flight for unaccompanied minors

In many families, parents or grandparents occasionally have to send kids from one family group to another , creating situations in which kids fly alone. Airline standards about the minimum travel age for children flying alone vary, though, and policies for unaccompanied minors on flights is one area where the big U.S. airlines do not march in lockstep.

How old do you have to be to fly alone?

The minimum age for children to travel alone as adults paying adult fares varies: Kids have to be 12 years old to fly alone on domestic flights with Hawaiian, Southwest, Air Canada, and WestJet; 13 years old on Alaska; 14 years old to fly as an adult on JetBlue; and 15 years old on Allegiant, American, Delta, Frontier, Spirit and United. 

International age limits also vary by airline, and some airlines don’t allow unaccompanied minors on international flights.

Can kids younger than 5 years old fly as unaccompanied minors?

For a variety of reasons, including the fact that flying with kids can be difficult even under the best conditions, children younger than 5 years old cannot travel as unaccompanied minors under any circumstances. For children between 5 years old and whatever the minimum adult age is on their chosen airline, most airlines provide special unaccompanied minor service for a fee. 

Of the 12 large North American airlines, only Allegiant and Frontier do not offer unaccompanied minors the option to fly. Many airlines also offer unaccompanied minor service for children a few years over the minimum adult age, which can be a good fit for families nervous about teenagers traveling alone.

Unaccompanied minor services and fees

Unaccompanied minors are carefully controlled and monitored by airline personnel throughout the boarding, flight, and arrival phases of the trip. Airlines require that unaccompanied minors be delivered to the airline by adults with the proper documentation and retrieved at their destination by other documented adults.

Typically, airlines avoid booking unaccompanied minors on the last flight of the day or on flights likely to be disrupted by weather or other factors . Also, bookings on code-shared flights are not allowed. Most airlines limit unaccompanied minor service to nonstop or direct flights. Alaska, American, and Delta allow unaccompanied minor bookings on some connecting flights for kids ages eight and older, with various schedule and route limitations. 

The big U.S. airlines charge a base fee of $150 each way (though sometimes the fee covers multiple children traveling together) plus the applicable adult fare; other airlines charge the same or less. On the airlines that allow unaccompanied minors on international bookings, conditions around children flying alone on those flights are even more stringent. Most big international airlines offer similar services, though specifics vary by airline and country.

Parents of responsible tweens and young teens would do well to compare flights and airlines , since the minimum age at which children can travel unaccompanied ranges so widely. Also, with unaccompanied minor fees in the range of $150 each way, having a family member buy a round-trip ticket to accompany kids one way on a short trip may actually be less expensive.

Minimum age to travel alone: Taking the train

Thinking about sending your child on the train instead? The minimum age to travel on Amtrak without an adult is 16 on most routes. However, Amtrak offers unaccompanied minor service between staffed stations on some trains for children between the ages of 13 and 15.

Unaccompanied Minor Program

Program details, unaccompanied minor travel journey.

If your child is traveling alone as an unaccompanied minor, an adult (18 years old or older) must accompany the minor through the check-in process and pick up the child at their destination. Review the process to help your unaccompanied minor prepare for their flight.

How to Book

To determine eligibility and book a reservation for an unaccompanied minor, you must contact Reservations at 800-325-8847 to ensure that the travel is permitted and correctly documented. When you book, the adult making the reservation will provide a 4-digit PIN configuration that will be required to make any changes to the itinerary.

Getting Ready to Fly

When it’s time to travel, we recommend talking with your child about the journey, reminding them only to speak to Delta Air Lines representatives if they need anything. Remind them not to leave the gate area at any time and notify Delta if your child has any special needs. When packing, we recommend bringing:

• Snacks, games, books or other entertainment
• A single, small carry-on like a backpack, so nothing’s left behind
• A checked suitcase for larger items, which your child and accompanying adult can pick up after their flight
• An ID card contact information attached to your child’s carry-on bag or jacket

Required Check-In Documents

When you arrive at the airport, please see a Delta Airport Customer Service Agent for information regarding drop-off and pick-up for unaccompanied minor travel. You will receive a  wristband for your child to wear in-flight and create a package of boarding documents and ID for your child to use as they travel. At check-in, the accompanying adult must provide the following:

• Photo ID (license, passport, etc.)
• Address (as shown on ID)
• Contact phone number
• Name, address and phone number of the adult meeting the unaccompanied minor at their destination

Unaccompanied Minor Boarding & Takeoff

A parent or designated accompanying adult must take the unaccompanied minor to the departure gate and remain until the flight has left the ground. 

If the minor is connecting though another city, the child will be assisted by a Delta or business partner employee.

• Delta recommends that children be seated in the rear of the aircraft to be near a flight attendant for safety
• For questions or concerns, please contact Delta Air Lines at 800-325-8847 (U.S./Canada/Guam/Puerto Rico/U.S. Virgin Islands) or find numbers for all other locations

Delta Sky Zone

If your child has a connecting flight through Atlanta, Cincinnati, Detroit, New York (JFK), Los Angeles, Memphis, Minneapolis, Salt Lake City or Seattle, we offer Delta Sky Zones for their entertainment. In these children-only areas, children flying alone can wait for connections, use complimentary phones to call parents/guardians and take advantage of activities like books, toys and video games. Staffed by Delta representatives, your child will find staff members always there to help them feel secure and comfortable.

Unaccompanied Minor Pick-Up

A valid ID must be presented and signature captured of the person meeting the child. Delta will not release to anyone other than the person named. A parent or accompanying adult should report to the destination airport two hours before scheduled arrival to obtain a gate pass. Please note:

• If the pickup person at the destination changes, the accompanying adult must call Delta at 800-325-8847 to provide the new information.
• Upon arrival, if someone other than the person named at check-in is at the destination to pick up the child, a Delta representative will contact the original accompanying adult to verify the identification of the pickup person at the destination.
• The pickup person at the destination will typically be issued a gate pass to pick up the unaccompanied minor at the gate. In some locations, the pickup person will be directed to the local Delta Baggage Service Office for pickup.
• At the point of departure, the accompanying adult must remain at the gate until the flight is off the ground.

Unaccompanied Minor Program Fees & Rules

The Unaccompanied Minor Program requires a fee of $150 USD/CAD/EUR each way, with CAD and EUR used when departing Canada or Europe. This fee applies to travel within the United States and International on both nonstop and connecting flights, in addition to the ticketed adult fare.

• The $150 fee is mandatory for children ages 5-14, and for 15-17-year-olds if a parent chooses to enroll in the unaccompanied minor program
• The fee covers up to 4 children if multiple children, such as siblings, are traveling together
• The fee can be paid one-way or round-trip at the time of check in or in advance by calling
• Unaccompanied Minors must be ticketed on an adult fare
• Travel is permitted on Delta and Delta Connection
• Travel is permitted on Domestic and International itineraries
• Unaccompanied Minors can only connect to other Delta, Delta Connection, Air France, KLM and Aeromexico flights

• International flights
• Connecting to/from international flights
• Connecting to markets with only one flight per day

Unaccompanied Minor Frequently Asked Questions

A Delta Air Lines employee will take your child on board before general boarding begins. This allows time to:

• Introduce your child to the flight attendants
• Introduce your child to the cockpit crew, time permitting
• Take your child to his or her seat and assist with carry-on items
• Familiarize your child with the safety features of the aircraft
• Advise your child of lavatory locations
• Inform your child if assistance is required to contact a flight attendant and to remain in their seat upon landing as a flight attendant will get them when it is time to deplane

No. You will be asked to say goodbye in the terminal area because access is restricted to ticketed passengers only. We do ask, however, that you stay in the gate area until the child's plane takes off in the event the flight returns to the gate.

A badged employee will meet your child's arriving flight. If your child's connection time is short, the unaccompanied minor escort will take your child directly to the connecting departure and will escort him or her on board.

If your child's layover is longer, the employee will take him or her to the Delta Sky Zone or other secure location, and turn the ticket and the Unaccompanied Minor over to the next Delta Air Lines representatives in the room (the employee keeps your child's documentation until it is time to go to the connecting flight). Another representative will escort your child onto the connecting flight at the appropriate time and introduce him or her to the flight attendants.

If we have any indication that your child’s flight may not operate as scheduled, we'll advise you and suggest that you book travel for another day. If the delay or cancellation occurs en route, Delta employees will:

• Rebook your child on the next available departure to their destination
• Stay with your child until they can be boarded on an alternate flight
• Contact the person at the destination who is designated to pick up the child and/or the person listed as the emergency contact. We will continue to attempt contact until contact is made

Under very rare circumstances, an overnight may be required (e.g. a major snowstorm). In these situations, we will provide overnight and meal accommodations for your child. And a Delta employee(s) will provide supervision to ensure your child's safety during an overnight stay. You will be contacted with pertinent information if this unusual circumstance occurs.

Enrollment in the Delta Air Lines Unaccompanied Minor program is mandatory for children 5 to 14. If you prefer that your 15 to 17-year-old travel without supervision, please advise the agent at the time of the reservation and it will be noted. Your child will be expected to handle boarding and deplaning as well as transfers to connecting gates on their own.

• Remind your teenager never to leave the airport for any reason unless accompanied by a badged Delta employee or uniformed police officer until they have reached their destination city
• She or he should never seek help from or leave the airport with strangers
• Provide your teenager with instructions, phone contacts and a small amount of money for food in the unlikely event their flight is missed, delayed, canceled or rerouted
• Remind your teenager that they can seek the assistance of any Delta employee if they have questions, concerns or need reassurance
• Remember most hotels will not accept young people who are not accompanied by an adult

Yes. If you are dropping off or picking up your minor but opted out of the Unaccompanied Minor program, we will issue you a pass to accompany your child to the gate. Please check with an airport agent at the time of check-in to have the gate pass issued.

Due to safety concerns, gate passes are not issued for the person picking up the minor (15-17) unless they are enrolled in the Unaccompanied Minor program.

Yes. International UMNR travel resumed April 1, 2021. However, there are some restrictions on travel based on individual country requirements or travel on other airlines. Contact Reservations at 800-325-8847 for more detail related to international travel for UMNRs.

Children traveling alone and other fees - Canada

Unaccompanied minor service

Our service includes:

• Early boarding to allow extra time to get settled and meet the flight attendants
• Kids-only lounges in our hub cities for flight connections
• An airport escort to help your child to the gate for flight connections
• Escorting the child to the authorized adult picking them up when they land

Keep in mind, our flight attendants will be busy with onboard duties and can’t continuously monitor your child during their flight. Let your child know to ring the call button if they need anything.

Age and flight restrictions for children traveling alone:

We don’t allow children to travel alone when their trips include:

• Flights on another airline including codeshare and one world® partners
• Ground or co-terminal connections where the child must transfer from one local airport to another
• The last flight of the day from the final connection city (unless it’s the only flight)

Note: Children ages 2 – 14 can travel as an 'accompanied minor' with someone 16 or older.

Booking your child's trip

Unaccompanied minors need to be booked by phone.

Contact Reservations

Preparing for travel

Whether your child has traveled alone or this is their first time, we recommend talking with them about the trip and what to expect. Assure them our team is there to help keep them safe.

Some helpful tips to prepare:

• Point out our team uniforms at the airport. Remind your child to ask for help only from a uniformed team member.
• Write down phone numbers for your child.
• Pack games, books and money in one small carry-on.
• Food and drink service is limited, so we recommend packing snacks for your child to enjoy during their flight.
• Attach an ID card and contact information to your child’s carry-on bag or jacket.
• Fully charge any electronic devices, and don’t forget to pack chargers and headphones.
• Be sure your child knows to wait for a team member to walk them off the plane when they land (this includes older children using our service).

Note: We don’t hold or give personal medication to an unaccompanied child.

At the airport

Check-in and required documents.

Arrive at least 2 hours before the scheduled departure time of your child’s flight and speak with a ticket counter agent. Children traveling alone can’t check in online or at the kiosk.

You’ll need to fill out an unaccompanied minor form and any necessary Customs and Immigration documents for the day of departure. This form must remain with your child during their journey. At check-in, parents / guardians will also need to provide:

• A birth certificate or passport as proof of the child’s age
• The adult’s government-issued photo ID with their current address
• Your phone number so we can contact you
• The name, address and phone number of the adult meeting your child at their destination

Once your child is checked in, the ticket agent will give you a security pass from the airport ticket counter so you can take your child to the gate.

Boarding and takeoff

For a smooth departure:

• An adult must take the child to the departure gate and stay until the flight is airborne.
• When you get to the gate, tell the gate agent you have an unaccompanied minor traveling on the flight.
• We’ll board your child early so they can meet the flight crew and learn about the plane’s safety features.
• The gate agent will let you know when the flight is airborne and you can leave the airport.
• Please contact the adult picking up your child to let them know they’re on their way.

During the flight

Our flight attendants will check on your child as duties allow, but they can’t continuously monitor your child throughout the flight.

Please remind your child to:

• Tell a flight attendant if he or she needs assistance or feels discomfort.
• Follow plane safety instructions, like wearing their seatbelt.
• Wait for a uniformed team member to escort them off the airplane once it arrives at the gate.

Unaccompanied minor lounges

If your child has a connection, we have lounges for unaccompanied minors in these airports:

• Charlotte, NC (CLT)
• Washington Reagan, D.C. (DCA)
• Dallas Fort Worth, TX (DFW)
• New York, NY (JFK and LGA)
• Los Angeles, CA (LAX)
• Miami, FL (MIA)
• Chicago, IL (ORD)
• Philadelphia, PA (PHL)
• Phoenix, AZ (PHX)

While there, your child can wait for their connection and play games while supervised by American business partner personnel. These staff members will take your child outside the lounge to buy food and drinks, but they won’t be allowed to walk around outside alone.

Arrival and pick-up

For a seamless pick-up, don’t forget your government-issued photo ID. You’ll need to show it to get a security pass and meet the child at the gate (in the U.S.). You’ll also need to show it before we release the child to you.

We suggest arriving at least 2 hours before the child’s scheduled arrival so you have enough time.

Flight status and notifications

Stay connected with your child’s journey with flight notifications and remind the adult picking up your child from the airport to do the same. Be sure to get alerts for all flights in their trip.

Flight status

Flight delays and cancellations

We’ll call the contacts on the unaccompanied minor form and arrange an alternate flight if your child is unable to make a connecting flight due to delays or cancellations.

In the rare case that your child needs to stay overnight because of a missed connection, we’ll arrange for overnight accommodations, meals and supervision. We’ll call if this occurs.

Young adults (15 – 17 years of age)

If your young adult isn’t using the unaccompanied minor service and their flight is delayed or canceled, they will be accommodated as an adult customer. Keep in mind, many hotels won’t allow young people to check-in unless they are accompanied by an adult. Please remind them not to leave the airport for any reason unless they:

• Are accompanied by a uniformed team member or police officer
• Have spoken with a parent or designated adult

Please tell your young adult to speak to a team member if they have questions or need help.

Children traveling outside the U.S.

You may not be able to escort your child through security in some airports. If this is the case, a team member will take your child to the gate and stay with them until the flight departs.

Children under 18 may need a Letter of Consent to travel internationally without both parents.

Country-specific regulations

Some countries have additional restrictions for children traveling with guardians or as an unaccompanied minor.

If your child is traveling unaccompanied or with only one parent, you’ll need:

• The child's birth certificate
• Notarized travel authorization from both parents

The Brazilian Embassy or Consulate must issue, authenticate or legalize this travel authorization.

Contact the consulate in the child’s country of residence or check the National Council of Justice site for more information.

Brazilian National Council of Justice (CNJ) guidelines Opens another site in a new window that may not meet accessibility guidelines

• The signature of a parent or legal guardian
• Authentication by local Police Headquarters

For children with a document proving another nationality (not Italian), check with the local Italian embassy or consulate in their residence country or the embassy or consulate of their destination country for requirements.

Children younger than 18 (at time of travel) and traveling alone to or from Mexico must have a travel authorization letter. This letter must be:

• Signed by at least one parent or legal guardian

All children should present their own passport and meet the requirements of their destination.

Spanish authorities require that all Spanish children traveling alone, with only one parent or with a third party have a travel permit requested by the parents or legal guardians. This permit must be issued by one of these: Police, Civil Guard, Notary’s Office or Town Hall.

For children with a document proving another nationality (not Spanish) and living in Spain, go to the consulate to complete the necessary paperwork.

Parents typically want to travel with their children, but that isn't always possible. Your children may have to travel by themselves for a variety of reasons.

So, that leads parents to ask, "Can minors fly alone?" And, "How old do you have to be?"

The answer depends on the airline and the type of flight you want to purchase. Learn about the rules for each airline, how much they charge and what restrictions govern unaccompanied minor flights.

Why do children fly by themselves?

Here are a few of the reasons why your child may need to fly alone.

Financial . Plane tickets can be expensive, and some families may not be able to afford enough tickets for parents and children.

Divorced parents

Time off work . Parents may have difficulty getting time off work to travel with their children. Whether the child is off to camp, going to see family or other reasons, they may need to travel alone.

Which airlines allow unaccompanied minors to fly?

Flying as an unaccompanied minor is available on major carriers Alaska, American, Delta, JetBlue, Southwest, Spirit and United Airlines.

At what age can you fly alone?

The minimum age to travel alone varies among airlines. While there are no specific federal laws on how old a child must be to fly alone, no major U.S. airline allows children under the age of 5 to fly by themselves.

Unaccompanied minors may also travel internationally if they have a passport and meet the airline's requirements.

Depending on which airline your child is flying and their age, the airline may require them to fly nonstop or on a direct flight that doesn't require a plane change. As they get older, some airlines allow them to take connecting flights.

Once a child turns 15, most airlines allow them to fly alone without unaccompanied minor rules and fees. Some airlines allow children as young as 12 to travel without these procedures.

Child travel policies by airline

The travel policies for unaccompanied minors vary significantly by airline. Depending on your child's age and circumstances, your child may not be able to fly on your preferred airline.

Alaska Airlines

Alaska Airlines' Junior Jetsetters program is an unaccompanied minor service for young fliers aged 5 to 17 on domestic and international flights. It costs $150 each way per flight.

The service is optional for young adults ages 13 through 17 years old.

American Airlines

American Airlines’ unaccompanied minor service is required for children ages 5 to 14 traveling alone. Children ages 2 to 14 can travel as unaccompanied minors with someone who is 16 years and older.

The American Airlines unaccompanied minor fee is $150 each way (plus taxes) and must be booked over the phone. The fee also covers additional siblings on the same flight. It includes early boarding, kids-only lounges in hub cities, an airport escort and more.

There are different levels of restrictions based on your child's age:

0 to 4 years: Cannot travel alone.

5 to 7 years : Nonstop flights only.

8 to 14 years : Nonstop flights and connecting flights through select hub cities.

15 to 17 years : Unaccompanied minor service is optional.

You cannot use this service on code-share or partner-operated flights, the last flight of the day or overnight connecting flights.

Delta Air Lines

For a Delta unaccompanied minor fee of $150 each way, up to four children ages 5 to 14 can travel together as unaccompanied minors. Minors between the ages of 15 and 17 can also use this service, but it is not required. With this service, Delta provides an employee escort and special amenities for children during their trip.

At select airports, children also have access to the Delta Sky Zone. This kids-only lounge featuring video games and snacks is a secure area for children to relax between flights.

Unaccompanied minors receive a bar-coded wristband that tracks their journey. Parents are allowed to accompany their children through airport security to the gate area until their departure.

Frontier Airlines

Frontier Airlines eliminated unaccompanied minor travel for children under the age of 15 in 2018. All children under 15 must travel with an accompanying adult to fly with Frontier Airlines.

Children ages 15 and older are treated as adults when flying Frontier. They do not receive special accommodations or airline escorts like those available with other airlines.

JetBlue Airways

Travelers between the ages of 5 and 13 are considered unaccompanied minors with JetBlue. Under the JetBlue unaccompanied minor rules, they can take only nonstop flights.

Additionally, there can be a maximum of three unaccompanied minors on each flight. So, you may not be able to pick certain flights if there are already too many unaccompanied minors on that flight. There is a fee of $150 each way for each child for this service.

Once children reach their 14th birthday, JetBlue allows them to travel alone without restrictions.

Southwest Airlines

Children ages 5 to 11 are required to book an unaccompanied minor ticket on Southwest. Parents can book these tickets online, over the phone or at the airport ticket counter.

The Southwest unaccompanied minor fee is $100 each way per child and due at booking. These fees are refundable if the minor does not travel or if they're later joined by an accompanying passenger age 12 or older.

Parents can get a gate pass from the Southwest ticket counter to bring their children through security and deliver them to their departure gate. At the gate, the child receives an unaccompanied minor lanyard that holds their paperwork and must be worn throughout the duration of their flight.

Unaccompanied minors cannot travel on connecting flights. They must fly nonstop or on a flight that does not require a change of planes. These travelers also cannot travel on flights that require an overnight connection.

Passengers 12 and older are able to travel as "Young Travelers" on Southwest. While Southwest allows these younger passengers to travel alone, parents should consider whether their child is capable of navigating the airport by themselves, dealing with flight disruptions and other scenarios they may face.

Spirit Airlines

The Spirit unaccompanied minor fee is $150 and its policy is as follows:

4 Years and Younger Children must travel with another guest at least 15 years of age.

5-14 Years children can fly on direct flights only and require booking the unaccompanied minor service.

15 Years and older guests are not required to have Unaccompanied Minor service, but it is an option.

Young fliers are offered a snack and drink as part of the service.

United Airlines

On United Airlines, unaccompanied minor service is required for children ages 5 to 14 and is optional for passengers ages 15 to 17. These tickets can be purchased online, over the phone or at the airport.

At the airport, you'll check your child in at the airport ticket counter, where they'll receive a special wristband and envelope for their travel documents. Parents can get a gate pass at U.S. airports to walk their children to the gate.

To use the unaccompanied minor service, children must be booked on a nonstop United or United Express flight. The fee is $150 each way for up to two kids, $300 for up to four kids and $450 for up to six kids.

Comparison of unaccompanied minor fees by airline

This chart summarizes the ages and fees for unaccompanied minor travelers.

The bottom line

Even if you cannot travel with your child, it is still possible for them to travel alone. If you're considering allowing your child to travel without you, you may wonder, "How old do you have to be to fly alone?"

While no major U.S. airline allows children under the age of 5 to travel solo, the rules and fees vary considerably for children ages 5 to 17. In some cases, children as young as 12 years can fly without any restrictions.
