Nothing about this flight was enjoyable from the minute I arrived at the airport and dealt with frontier employees. This happens every time I fly with frontier and the way they treat customers is abominable

Nothing the flight was canceled. Made us sit around for hours. Then the flight crew tied down. It was ridiculous. Had to book a different flight another airlines in Saint A hotel overnight.

We waited and waited, there were no updates or announcements, and then the flight left from a different gate. We had to scramble and get a very expensive last-minute flight on Southwest to SFO.

The flight itself was great. But it was delayed 6 hours and other than text after text advising flight would be even later each time, there was no communication. Did not know why. Had we been advised of what the issue was it may have helped. We were left waiting in the airport and couldn’t even get a cup of coffee as everything closed. Once flight did arrive around 1am boarding and takeoff was quick, crew was nice.
