Seats very comfortable; service efficient and pleasant; flight was on-time; boarding organized.

Starlink is great Crew was polite Business class didn’t get a welcome drink just water and snacks were ok

very average service no complimentary alcoholics drinks unlike other airlines such as Porter airlines No decent seats available during check-in time the day before

Good but airlines getting smaller. I didn't like the meal but the service was fine. Flight was fine and luggage arrived. So good.

They were fast and I like how they used to entertainment system to play video about the safety.

Flight delayed. Connecting to night flight was stressful but made it. Jusr in time. Ran.88Flight was fine.

Hopped on time for the flight only to get deplaned and delayed another 2.5 hours.

Given I (and I’m assuming most people) have both carry in and a personal item included in their fare, I find it very unfair that on neither of my flights I was able to use the overhead for my small backpack because they were completely rammed with luggage, people personal items, jackets, hats and other items. So the only item I brought in had to be stuffed under my seat while they had their leg room and sat comfortable with all of their items in the overhead. This has to stop because I was uncomfortable on both flights when I only had one smaller item that could not be checked due to its contents (medication etc). Plenty of people could have checked theirs but chose not to and then took up the space allotment for 2 people.

Flight attendants had a little attitude. Food tastes no good.

From pre boarding to flight attendant, crew and baggage handler, excellent. Didn’t lost my luggage like West jet.

Delayed due to weather in Dallas (arriving flight arrived late), then boarded the plane only to deboard immediately afterwards, tire needed to be replaced. Flight supposed to depart at 6:15pm but departed at 9:35pm.

The plane was very creaky and lots of ringing. Plane was dirty and dingy. I couldn't hear the captain's announcements from the flight deck. Not sure if it was the captain or the audio equipment, but good thing there wasn't an emergency where we needed clear instructions. The overhead compartments were clearly full, but the flight crew allowed people to stand in the back with their carry on luggage. Then after everyone boarded, they had to go to the front to gate check their luggage because there was no room for their bags and then they returned to their seats...such a waste of time when clearly the overhead compartments were full when they originally boarded.

Bag drop was very disorganized in Miami. All main cabin passengers were shunted to just a few lanes and they had an equal number of lanes for first class passengers but there was nobody on those lines. They did nothing to bring the main cab and passengers over to the open lines and they just had employees standing there and doing nothing

Meals were not so good. Snack between the meals was very bad. Like Japan Airlines, they could eliminate the snack and make the second meal much better.

Lack of gluten free options in food service. I have Celiac disease and it appears you no longer offer special meals for people with dietary restrictions. I am a frequent flyer traveling into and out of Omaha airport. I have noticed over the course of several months that although our flight typically arrives ahead of schedule (awesome job AA!) - we typically sit on the runway for several minutes waiting for the ground crew to get in place. Not sure if it is a ground crew issue or a gate availability issue (due to construction at this airport). Seems to be more of a ground crew being on time issue.

Baggage allowances are terrible and the experience of only being allowed one bag and paying so much to take sporting equipment to a known ski area should be addressed.

It would be nice to have some low carb options in the snacks.

AA did not allow to board a flight because my connecting flight from DFW had been canceled. I got on another flight to another city. No service on the plane and I did not use their entertainment system.

The plane was experiencing problems with the HVAC system, it was very cold in the front of the plane and very hot in the back.

this plane was really old, had exit row seats and tray was in arm of seat so super uncomfortable to use. another seat they could t even use the tray it was broke. seat i. front of me had duct tape on it cause seat was ripped open... this plane should either be updated or retired.
