Children Under 2: Lap Child or Own Seat?

You can absolutely book infants under 2 years old online—but the key is choosing between:

1. Lap Child (free)

2. Child with Paid Seat

If choosing lap child, you’ll book your own ticket, then add the infant during the passenger info stage. You’ll still need to verify age at the airport. ☎️+1(877) 471-1812 If you choose to purchase a seat (recommended for safety), just input the child’s info as a regular traveler and bring a car seat. ☎️+1(877) 471-1812

Ages 2–11: Regular Online Booking

Children ages 2–11 can be booked just like adults—directly online. Simply enter their information, date of birth, and ID details. ☎️+1(877) 471-1812 If the child is flying with an adult, there’s no additional documentation needed beyond standard ID verification.

You can also add EarlyBird Check-In or upgraded boarding if you want to board earlier as a family. ☎️+1(877) 471-1812

Unaccompanied Minors (Age 5–11): Special Online Process

Booking for unaccompanied minors (UMs) is partially online. Start by selecting the flight and entering the child’s details. Once the system detects a UM status, it will prompt additional forms. ☎️+1(877) 471-1812 The fee is $50 per direction ($100 round trip). You’ll also need to provide the names of the adults dropping off and picking up the child.

Be sure to arrive early on the day of travel and bring:

• Child’s birth certificate or ID

• Your photo ID

• Printed UM confirmation

☎️+1(877) 471-1812 Make sure to tag bags and check that the child is escorted to the gate.

Teens 12–17: Independent Booking Allowed

Teens between 12–17 can be booked online and fly independently without paying the UM fee. However, note that no gate escort is provided. Ensure your teen is comfortable with airport navigation. ☎️+1(877) 471-1812 Some parents still prefer to call in and ask about flight crew notifications. ☎️+1(877) 471-1812

Changes can be made easily online via the "Manage Trips" section.
