The flight attendants were extremely sourly and borderline rude. I did not feel appreciated as an AA customer once.

The flight attendants were extremely sourly and borderline rude. I did not feel appreciated as an AA customer once.

Movies on my phone are great. It would be nice to have a gluten free snack option.

As we approached Denver, we encountered quite a bit of turbulence. I know this can sometimes be the case as I frequently fly this route but not on American. My gripe: Usually a pilot or co-pilot alerts passengers to the possibility of turbulance ahead of time. This did not occur nor did he communiucate during what was a pretty rough ride.

Liked that it was on time. Staff professional and friendly.

Terrible. Our luggage was delayed and couldn’t be delivered for several days. We got bad information from the airline agents at baggage claim. We had to pick up our car so we wouldn’t be charged for an extra day. We got lost in the maze of airport parking. The baggage claim agents didn’t offer us any compensation for our extra time and expense. We are tired, hungry and very frustrated.

Mechanical delay and no compensation. Missed connection as a result of their delay. Mediocre performance and service. Horrible airline currently with horrible culture.

Any sort of gluten free snack option would be nice

Crew was late. Baggage was late. 2hs inside the plane waiting fro de-icing and traffic. A 3:30hs flight ended up being almost 6hs inside the airplane.

Delay 14 hours! Missed all connections and had to fly different airline the next day.

Terrible customer service playing as usual was late and the Denver tried to get to a bus, but it already scheduled for service to Fort Collins, but because they could not help me at all at the baggage service desk. I missed the bus by one minute after they kept me arguing about how to handle my bag which have not gotten onto the carousel, Customer Service and Denver at the baggage claim customer service had the nerve to say she did not fly the plane and the responsibility of the bag was all mine. Pathetic.
