10.0 Wonderful
Weather in Atlanta necessitated an hour's hold on the tarmac before we could leave Detroit. The plane was packed, and I expected some surliness. But no! The crew was fantastic (jovial even!), responsive to people's needs, and kept us informed. Consequently, the passengers took the delay in stride, and what could have been an ugly situation turned out to be no more than a minor inconvenience. The crew were the stars here.

Flight cancellations. Delayed boarding

They did everything right and everything happened right on time.

6.0 Okay
We were skipped when the snack cart passed and then the attendant said we weren’t . I am disabled and was in a row toward the back of the plane which was very difficult for me to navigate. Disabled people should not be forced to walk the plank.

2.0 Poor
My flight was delayed and I got back around 3.5 hours later than expected. I had to get a new connecting flight

It was very pleasant from boarding to exiting
J
2.0 Poor
Seat was too small for someone as tall as I am. I was behind an exit row making my leg room even less. There flights were delayed by multiple hours. Some weather related and others staff related. The plane was hot. Horrible experience.
J
2.0 Poor
The Atlanta airport had thunderstorms, which caused our flight to be delayed by multiple hours. Once we were able to board.the gate agent was rude and was trying to rush us onto the plane because the team in the plane was about to run out of hours once we were all aboard the plane they ran into an issue where the catering truck was filling up the back of the plane and they left and had to come back because they didn’t fill it up all the way, causing even more of a delay. My seat was very tight. I didn’t have a lot of legroom overall this was a miserable experience.

I want my money back
