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.
