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

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.

Flight was a little late taking off. Seats are too upright, no ports to charge devices, no wifi, no entertainment

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….

See my previous comment which is mostly about our flight from Phoenix to SFO

The check in at the airport was awful. Told I need to pay for a bag. The item was taken at screening. I went back to get my $ back and they gave me a coupon with a QR code that doesn’t work. Worst costumer service ever!!!!!

4 hour delay because they used our aircraft to fly a different segment (per the captain)
