When one or more of the passengers on a reservation are 13 years of age or younger, Frontier will guarantee adjacent seats for the child or children and an accompanying adult (over age 13) at no additional cost for all fare types subject to limited conditions specified below.
- Child and accompanying adult are on the same reservation
- Adjacent seats are available at the time of booking
- Adult either chooses seats for the entire reservation or skips seats for the entire reservation, and does not make changes to seat assignments once assigned to them
- It is physically possible based on seat layout to seat the number of children traveling next to the accompanying adult(s).
Although Frontier will provide adjacent seats if available at the time of booking, Frontier might not provide seat assignments right away. Frontier will provide the customer the adjacent seating assignments no later than the day before scheduled departure of the flight.
