I did not enjoy the trip home on Frontier for several reasons: there is too much cost besides the flight, which was more than I would normally pay, then having to pay for luggage, and carry-on, seat (if you want to reserve when booking) then you must pay over $3 for a can of soda, and $4 for a snack. A cup of water is free.

Did not realize seats did not recline. Best to travel in an exit row... No question

I strongly dislike Frontier. I find them barebones, the seats not particularly comfortable, the nickel and diming is maddening, the app is TERRIBLE - super confusing to navigate, and the last 4 frontier flights I have flown have been on AVERAGE 2 hours late, one ruining a fancy night out in Vegas with reservations made well in advance, which was nodded to with a measly 5000 miles, which translates to almost nothing. At least credit a free checked bag or something.

8 hr delay. had to buy another ticket with another airline

Four and a half hour delay in total. What frustrates me most is the poor communication and disorganization.

The agent at check-in was strident, unwelcoming, and condescending to customers ahead of me.

9hrs delay and didn’t provided anything until after flight landed $75 voucher for fiuture travel no meals or anything.

They cancelled the flight then did nothing to help us rebook. It was awful - I won’t fly with them again

The truck that was refueling the plane drove away with the hose still connected to the plane and ripped part of the plane off with it

The boarding time. I was in Section 1 the lady in charge just let people in section 3 without see us. Make a line , I have to step out and ask her. We were in the line and she just take my ticket and that’s it, so if I don’t ask her she could leave us at the end! We paid more for that privilege and. She doesn’t care….
