While policies may vary across airlines, a 16-year-old is generally allowed to check in at the airport alone. However, they are considered unaccompanied minors and must adhere to specific procedures and requirements. For instance, Delta Air Lines mandates that unaccompanied minors present a valid ID to security personnel and can opt for services like a trackable wristband and a designated Sky Zone lounge. American Airlines requires unaccompanied minors to be booked by phone and for a parent or guardian to fill out the necessary forms and provide proof of identity and the minor's birth certificate or passport.

What You'll Learn

An adult must accompany check-in
While some airlines allow children between the ages of 15 and 17 to travel as standard passengers, an adult must accompany 16-year-olds during the check-in process when they are travelling alone for the first time. This is a safety precaution to ensure that the child is handed over to the airline's care. The adult will 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 the child during their journey.
At check-in, parents or guardians will also need to provide a birth certificate or passport as proof of the child's age, as well as the adult's government-issued photo ID with their current address. Once the child is checked in, the ticket agent will give the adult a security pass from the airport ticket counter so they can take the child to the departure gate and stay until the flight is airborne. It is recommended that parents arrive at least two hours before the scheduled departure time of the child's flight to complete all the necessary procedures.
In the case of Delta Air Lines, a parent or accompanying adult must also pick up the child at their destination. The adult meeting the child at the destination airport will need to provide a valid ID and signature, and only then will the airline release the child to their care. If the adult picking up the child at the destination changes, the accompanying adult must inform the airline beforehand.
For international travel, all children should present their own passport and meet the requirements of their destination. For instance, Spanish authorities require that all Spanish children travelling 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 the Police, Civil Guard, Notary's Office, or Town Hall.

Required documents
When it comes to air travel, a 16-year-old is generally considered capable of checking in and travelling alone. However, they are still considered a minor in most jurisdictions, and thus certain procedures and documents are required to facilitate their travel. Here is a list of required documents for a 16-year-old travelling alone:
- Valid Identification: The minor must carry a valid ID that proves their identity and age. This could be a passport, national ID card, or any other form of identification accepted by the relevant authorities and the airline. It is essential to check the specific requirements of the destination country and the airline beforehand.
- Travel Authorisation Letter: In certain cases, a travel authorisation letter may be mandatory. For example, Delta Airlines requires a travel authorisation letter for minors aged 15-17 travelling without a parent or legal guardian. This letter should be signed by a parent or legal guardian and authorise the minor's travel.
- Unaccompanied Minor Form: Some airlines, such as American Airlines, require an unaccompanied minor form to be filled out by the parent or guardian. This form includes important information about the minor's travel and emergency contact details. It must remain with the minor during their journey.
- Customs and Immigration Documents: Depending on the destination and the minor's nationality, specific customs and immigration documents may be necessary. For instance, if travelling to certain countries, visas or other entry/exit permits may be required. It is crucial to research and obtain any necessary travel authorisations beforehand.
- Proof of Relationship: In some cases, the airline or authorities may require proof of the relationship between the minor and their parent or guardian. This could include a birth certificate, adoption papers, or other legal documentation.
- Guardian's Identification: When checking in a 16-year-old minor, the accompanying adult may need to provide their government-issued photo identification. This helps verify their identity and relationship with the minor.
- Other Supporting Documents: Depending on the circumstances, other supporting documents may be beneficial or mandatory. For instance, if the minor has specific medical needs or is travelling with special equipment, relevant documentation may be required. Always check with the airline and destination country for any unique requirements.
It is important to note that requirements may vary slightly between airlines and countries. Therefore, it is always advisable to contact the relevant authorities and the airline directly to confirm the specific documents needed for a 16-year-old to check in and travel alone.

Unaccompanied minor forms
The policies and procedures for unaccompanied minors checking in at airports vary across airlines. Here is a step-by-step guide to the general process, along with specific details from American Airlines and Delta Air Lines:
Before Arrival at the Airport:
- Booking: Unaccompanied minors cannot check in online or at a kiosk. For American Airlines, bookings for unaccompanied minors must be made over the phone. Delta Air Lines also recommends contacting their Reservations department to ensure travel is permitted and to book a reservation.
- Documentation: It is essential to prepare the required documents before arriving at the airport. This includes an unaccompanied minor form, which must be filled out by the parent or guardian and kept with the child during their journey. Other necessary documents include any necessary Customs and Immigration forms, the child's birth certificate or passport as proof of age, and the parent's or guardian's government-issued photo ID with their current address.
- Preparation: It is recommended to talk to the child about the trip, what to expect, and any instructions they should follow. Provide the child with phone contacts and a small amount of money for any potential delays or emergencies. Pack games, books, snacks, and other essentials in their carry-on luggage.
At the Airport:
- Arrival: Arrive at the airport early, at least two hours before the scheduled departure time. Upon arrival, proceed to the check-in counter and speak with a ticket agent.
- Check-In: During check-in, the parent or guardian must present the required documents, including the unaccompanied minor form and proof of the child's age. The accompanying adult will also receive a security pass to escort the child to the departure gate.
- Departure Gate: An adult must accompany the minor to the departure gate and remain there until the flight is airborne. Inform the gate agent about the unaccompanied minor, and they will facilitate an early boarding process for the child to meet the flight crew and familiarise themselves with the plane's safety features.
During Transit and Arrival:
- Transit Lounge: Airlines like American Airlines and Delta Air Lines offer dedicated lounges for unaccompanied minors during transit. These areas provide entertainment, supervision, and assistance from airline staff.
- Flight Notifications: Stay connected with flight notifications to track the child's journey.
- Pick-up: The person picking up the child at the destination airport should arrive at least two hours before the scheduled arrival time. They will need to present valid identification and obtain a gate pass.
Please note that specific requirements, such as age restrictions and additional fees, may vary depending on the airline and the destination country's regulations. Always review the policies of the specific airline and consult official government sources for the latest travel requirements.

Travel authorisation letters
A 16-year-old can check in at the airport alone, but their treatment as a minor will vary depending on the airline and country. For example, Delta Airlines allows 15-17-year-olds to travel as standard passengers, provided they can present a valid ID to security personnel. However, American Airlines requires that children under 18 travelling alone be booked by phone and treated as unaccompanied minors. In such cases, an adult must accompany the minor through the check-in process and stay until the flight is airborne.
Regardless of the airline, a travel authorisation letter can be a helpful document to have when a minor is travelling alone or with someone who is not their parent or legal guardian. While it is not always required, it can simplify the travel process and reduce the likelihood of border officials questioning the authenticity of the minor's documentation. Here are some key points to consider when drafting a travel authorisation letter:
- Content and Format: There are no official guidelines for the content and format of a consent letter. However, it typically includes information such as the parent's or guardian's authorisation for the minor to travel, the accompanying person's details, the travel itinerary, and the dates of travel. It is recommended to include as much detail as possible and consult a lawyer if needed.
- Signatures: If neither parent is accompanying the minor, they can both sign one letter or use separate letters, especially if the children are travelling separately for part of the trip. In cases where one of the parents is deceased, the consent letter should be signed by the surviving parent, along with a copy of the deceased parent's death certificate. Any adult may witness the signing of the consent letter, but it is preferable to have a notary public witness and sign to enhance authenticity.
- Country-Specific Requirements: The definition of a "minor" and the entry and exit requirements vary by country. For example, Spanish authorities require all Spanish children travelling alone or with a third party to have a travel permit requested by their parents or legal guardians. It is essential to check the specific requirements of the destination country and consult the nearest embassy or consulate if needed.
- Medical Considerations: It is important to note that a minor travel consent form does not include permission to make medical decisions on behalf of the minor. If the consenting parent or guardian wishes to grant this authority, a separate minor child power of attorney form should be authorised.

Entertainment and supervision
While a 16-year-old can check in at the airport alone, it is recommended that they are accompanied by an adult. Here are some tips for entertainment and supervision for teenagers travelling alone:
Entertainment:
Most airlines provide entertainment options for unaccompanied minors. For example, Delta Air Lines offers a Sky Zone lounge for kids, with complimentary phones, books, toys, and video games. They also provide a trackable wristband and a personal escort for the minor throughout their travel day. American Airlines also has lounges for unaccompanied minors at certain airports, where they can play games under the supervision of American business partner personnel.
Additionally, some airports have dedicated play areas for children. For instance, Boston Logan International Airport (BOS) offers "Kidsport" play areas in three terminals. Major airports like Los Angeles and Miami have Centurion Lounges with soundproof family rooms featuring toys, books, TVs, and game consoles for teenagers. These lounges often require a specific credit card for entry, such as The Platinum Card® from American Express.
To keep teenagers entertained during layovers or delays, it is a good idea to pack books, games, and electronic devices. Snacks are also important to keep energy levels up, and some airports have kid-friendly snacks available in their lounges.
Supervision:
Supervision for teenagers travelling alone starts at check-in and continues until they arrive at their destination. An adult must accompany a minor during the check-in process and provide necessary documentation, including a birth certificate or passport as proof of age. The adult will also receive a security pass to take the minor to the gate and must remain until the flight departs. It is important to remind teenagers to ask for help only from uniformed staff members or police officers and never leave the airport alone unless accompanied by authorised personnel.
During their flight, flight attendants will be busy with onboard duties and may not be able to continuously monitor the teenager. However, they can always ask for assistance if needed. Upon arrival, a uniformed team member will escort the minor off the plane. If there are connections, they will be assisted by airline representatives or business partners. In the event of a missed, delayed, or cancelled flight, the airline will arrange for accommodations, meals, and supervision, and the teenager will be accommodated as an unaccompanied minor.
