The flight was canceled at the last minute and we got very upset as we had plans in which our schedule that affects a family reunion was in jeopardy.

Paying for first class and then they want $8:00 for wifi.

10 hour delay. Fuel spill. Crew had to drive to Indianapolis to a get a plane. The longest day of travel ever. Poor service.Little to no communication.

Easy flight, crew was polite & observant of all passenger needs as well as safety.

fine. only problem,,,, for some,,,,was that many people started trying to exit from the back of the plane,, . lots of irate people. there should be a flight attendant mid plane..to be sure that doesn't happen. The crew up front had no idea what was happening. One big guy started it..then a bunch of others followed his lead. could have gotten ugly... One man stepped in and questioned those rule breakers.. nothing bad happened,,,but......

We were delayed. We spent more time waiting on the plane than actually flying (it’s only a 37 minute flight). Other than that, it was fine.

Only offered water, no snacks provided, and it was cold on the plane, everyone was wearing sweatshirt or jacket in June. I asked for blanket, but crew said they didnt have anything and would turn the heat up, that didn't happen, so for 6 hours I remained cold.

Flight from New Orleans to Seattle to Anchorage was delayed for 3 hours My flight from Seattle to Anchorage was not rescheduled. I had to call the airlines to tell them to get a flight from Seattle to Anchorage they finally got me a flight If I hadn’t been aware of this problem I don’t know how long I would of waited in Seattle to get a flight to Anchorage!!!!!! Return trip from Anchorage to New Orleans in Seattle to New Orleans I was at the right gate when I realized something was wrong they had changed the gate without notifying the change l finally made it on time with minutes to spare & exhausted

I was at risk of not getting on the flight, as when I presented my boarding pass at the gate, it showed me as not having checked in. I was sent to the desk as the last of the other passengers boarded. The agent there said he could see that I had done all of my part and allowed times recommended, but it showed me as not checked in and he couldn't figure out how to correct it. He actually asked them to hold the flight as he struggled with it. He called for support, someone corrected it, and he printed boarding passes for both flights to reduce further issues. I did get on, and needed to ask someone to exit my seat.

Eddie, our flight attendant in the back was excellent. He was very kind and concerned for our happiness and comfort before and during our flight. He made the experience great. We had to deplane due to a ground delay and he made sure we had snacks and water to keep us comfortable while we waited. Overall, it was a great experience!
