I tried to check in at the kiosk, this should have been fast because I prepaid for my carry on and wasn’t checking a bag. The kiosk said I needed to get in line to check in and it was a long line. Once I got to an agent, 35 minutes before my plane was to leave, he said I missed checkin and would have to be rescheduled. This new flight was 4 hours longer and then he forgot to return my passport to me, luckily he found me on the way to the restroom. I will do my best not to fly Frontier again.
