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)

Lost baggage on my connecting flight. 24 hours later, still no update on my bags.

I had to cancel within 1hour of the reservation an they put you through hell to . no live customer service desk. I'm handy caped and they make it almost impossible to cancel. They are steeling my money. You should not have that airline on your site. Contact me and I will give you all info. Of what the are doing to me just notable treatment they are set up like that to take people

Be prepared for crowds and chaos upon arrival at the Orlando airport
