Verified travelerFlew with Frontier-Jun 2025
Wish I had known the seats were so uncomfortable. Wish I had known checked bags and carry on bags were 75 each. Wish I didn't have to wait so long in line with only one clerk working. Wish I had known we were going to have to take a bus from the gate to our airplane. Wish I had known the seat space is smaller than any other airline I have flown. I do not recommend Frontier.

It’s a big airport ask where your gate is

Seattle is a busy gate. Find your gate first as connections may involve underground tram.
