Strollers and car seats
You can check a stroller and a car seat for free with Frontier Airlines. These items are not counted as part of your carry-on or personal item allowances. You are permitted to use your own stroller throughout the airport and check it at the gate just before boarding; it will be returned to you at your destination.
If you bring a car seat onto the plane, it cannot be used in the first row, any emergency exit row, or the rows directly in front of or behind an exit row. The airline suggests placing car seats in window seats. The FAA-approved AMSafe Aviation C.A.R.E.S. harness is also allowed on board.

Sitting together
Frontier Airlines guarantees that a child 13 years old or younger will be seated next to an accompanying adult (over 13) at no extra cost, provided they are on the same reservation and adjacent seats are available at booking. This policy applies only when the child and adult are booked on the same reservation.
The free adjacent seating is also conditional on there being available seats next to each other at the time you book your tickets. To take advantage of this, it is best to secure your seats when you first make your reservation.
“Yes, if your reservation includes a child 13 or younger, we’ll guarantee they sit next to an accompanying adult (over 13) at no extra cost, as long as: You’re all on the same reservation Adjacent seats are available at booking”
