Unaccompanied Children travelling alone on United Airlines

United Airlines understands the needs of young solo travelers. United Airlines has developed specific policies and procedures to ensure the safety and well-being of unaccompanied children. United Airlines guidelines and requirements for children traveling alone are outlined below:

  • Age and Assistance: Unaccompanied children between the ages of 5 and 14 are provided with assistance by United Airlines. Minors over 15 are not considered unaccompanied minors and do not need special arrangements to travel.
  • Booking and Fees: When booking a flight for an unaccompanied child, it is important to inform the airline at the time of reservation. The fee varies depending on the itinerary and can be paid at the time of booking or at the airport.
  • Check-In and Documentation: Arrive at the airport 90 minutes before departure on the day of travel. Parents or guardians must provide a government-issued photo ID and sign the unaccompanied minor form. This form contains important information about the child, such as emergency contacts and special instructions.

Documents required during travel with children/Infants

Planning a trip with children or infants requires all the necessary documents to ensure a hassle-free and smooth journey. When traveling with children or infants, you should have the following documents on hand:

  • Every child should have a passport, regardless of their age. Passports should be valid for at least six months beyond the anticipated return date.
  • Visa: Children may need a visa to enter certain countries. Before traveling, research the visa requirements of your destination and obtain the necessary visa for each child.
  • Birth certificate: Especially for infants without passports, carry a copy of the child's birth certificate. Immigration authorities may require this document as proof of age and parentage.
  • Medical Documents: A copy of the child's medical records, including vaccination certificates and prescriptions, is always a good idea.

General Guidelines to travel with infants in Frontier Airlines

Planning and preparing for travel with infants is an important part of the experience. Here, we provide essential information and recommendations to ensure your travel experience with Frontier Airlines is as comfortable and stress-free as possible.

1. Booking your flight:

  • It is important to inform Frontier Airlines that you will travel with an infant when booking your flight. You and your child will then be able to make the necessary arrangements and be assigned appropriate seating.
  • Frontier Airlines allows infants (18 years or older) to travel free on an adult's lap. If you prefer a separate seat for your baby, you can purchase a ticket at the applicable fare.

2. Carry-on baggage:

  • In addition to their carry-on bag, parents traveling with infants are permitted to bring a diaper bag onboard.
  • You should pack diapers, wipes, formula, baby food, extra clothing, and any other necessary items for your baby's comfort during the flight in the diaper bag.

3. Infant seating:

  • On select aircraft, Frontier Airlines offers bulkhead seats with bassinets. The seats provide extra legroom and a bassinet attachment for your baby to sleep or rest during the flight. It is recommended to reserve these seats in advance since they are limited and subject to availability.

4. Safety considerations:

  • A child restraint system attachment strap or lap belt should be used to secure the car seat or CARES harness to the aircraft seat.
