Rated entertainment as Mediocre as there were major problems with the Infotainment system that took probably a half hour for them to fix.

Your crew could maybe answer the call bell at least one of the times I pressed it. I pressed it first time with 2.5 hours left in our flight bc my partner was hungry and wanted a sandwich. We finally got the sandwich with 40 mins left in the flight.

Half the bathrooms assigned to economy were out of action

Delta crushed it. Flight attendant in first was attentive and just never stopped. Honestly one of the best domestic flights I’ve been on.

They were an hour late and they didn’t have my wheelchair for me

The Flight crew didn’t serve us until about 1.5 hours into the flight because of turbulence but after it ended it was fine to move around. They served us water only and snacks and then NEVER, NOT ONE TIME came through to collect trash until right before landing about 1.5 hours later. There was absolutely no need for that. They crew was just standing around talking and visiting with each other and really never tried to see if we might want something besides water or even try to come pick up trash. This is VERY unusual for a Delta flight but it was not what I would have expected for a 4 hour flight.

The 1st class male crew member was very pleasant - the short female with round glasses , maybe in 50’s had no personality- never spoke when delivering my food, drink, & never smiled the whole trip! In fact looked annoyed when the boarding proses was happening- I would never hire this woman - unfriendly . Have never dealt with a crew member like her-

5-hour delay due to storms in Tanoa and airspace restricted by Miami traffic controllers.

A regional sized plane was used for a cross country flight with no overhead bin space. I had to "pink check" my laptop and my medications. I was NOT pleased!!!!

Absolutely nothing flight was cancelled and delayed for 2 days. Barely a heads up I want a full refund

Besides the flight cancellation, everything else was prefect. Kudos to Malaysian Airlines.

Operated by American Airlines. Very chaotic and the crew was bit rough responding any enquiries. Restricted leg space.. Qatar would have been better

Qatar airways from Doha to guangzhau was excellent big bird Boeing 777 more room and smoothly flight, I Love it

It was good no problems made it on time for the next flight overseas!

The made us waiting and held our passports and boarding pass making us miss our flights

Not impressed. Only allowed one carry on on such a long flight.

The flight was good but my neighbor had the vent open full power for the whole flight and because the air was blowing from the side instead of from the top and I got very cold and ended up with a sore throat.

Bad experience with the delay n long wait time for connecting flight after missing the connection flight from Doha.

Wore experience due to delay and took me 3 days to reach my destination.

All over with Qatar airlines my experience was really bad due to delays and then putting me on different airlines and after 8 hours of wait I had to listen to their is no plane to fly for another 24 hours. Wore experience ever.

My seat was broken. WiFi didn’t work. Gate crew at HOU were rude and condescending. Treated all the passengers badly. Bad experience, United.

First flight of the day… MINIMUM FUEL! 15 minute landing delay at HOU due to fog turned into a 2+ hour delay! Rather than circle, they had to divert to another city to refuel! Sat on tarmac at Austin to refuel. We ALL missed our connections! The crew, including pilots, were clueless. Crew was really a mess. At HOU, Untied employees were exceedingly rude to all. It was pitiful.

Food wasn’t very good, old business seating configuration on an old A340

An hour and a half late is UNACCEPTABLE. The negative impact to our family is unconscionable. And for the price we were forced to pay...

Standard flight experience, but there is only power at the seat to row 20 on the aircraft, on my initial check in it did not say that was the case

Not a fan of the diagonal partially enclosed business class seats or how they have to be converted to beds manually by crew. I prefer more isolation and user control for switching to lie flat.

No lounge access with “United First” ticket. False alarm about late flight, jeopardizing connection. Wrong meal. Loose power socket would not hold plug, could not charge device. In-flight access to text messaging did not work. Toilet seat on plane would not stay up.

We ended up with seats in the very back. So they did not recline. Have no idea why, we reserved and checked in very early. The isles were very narrow and the seats had very little leg room. But they did give us water, and a snack.

Energetic crew - flight full of swiftied going to Taylor's opening show in Paris! Long lines for bathroom made out kind of suck though

Check in etc was very good. As for on the plane, it was like flying in a freezer. It was so cold, i have flown for years and never been so cold on a plane. Staff on board said its always cold when flying which is a load of rubbish. They wouldnt put any heating on and now i have the flu because of this .

The preferred seats where awful. Impossible to use them again

The flight was short. However, my bag was delayed and was put on another flight.

Flight attendant was incredible. Very efficient, friendly and pleasant. Patricia was one of the best I have ever seen. Please give her a big raise!

Delayed multiple times. Boarding was ok but getting off the aircraft was a mess. So disorganized with staff trying to help the elderly but completely blocking path for anyone else to move. Bathroom was disgusting, probably caused by one of the customers but staff couldn't care less to help clean it. No one wanted to use it since the floor was completely soaked so everyone just lined up the other restroom while the staff just chit chat with each other while looking at us.

LIT to DFW - 3 hours late; the entire plane had been boarded before they told us there was a delay due to a weather-related ground stop in Dallas. DFW to MAY - 2+ hours late due to A/C needing to be repaired after everyone had boarded, then when we finally reach the runway, the First Officer timed out and we had to taxi all the way back to the gate and wait for a new one. I arrived in New Orleans 5+ hours later than I should have. Return flights were completely cancelled; rebooked through the app to fly through CLT instead of DFW. MSY to CLT had no issues, but CLT to LIT was delayed 1.25 hrs because flight attendants had not arrived to the airport yet. At least they didn’t make us all sit on the plane to wait for them. I should have driven.

Tray table was filthy when I sat down. I needed to have someone come clean it because there was food and stains on it WiFi didn’t work after paying for in flight WiFi Food was terrible and was not filling at all Chicken was rubbery Flight attendant had an attitude, interrupted me and wasn’t able to answer basic questions about the food selection such as “does the chicken have red sauce in it”. If your flight attendants are not going to know what is in the meals so we can make an educated decision based on dietary restrictions, they shouldn’t be on the plane. My 1.5 year old niece was sleeping and dropped her binkie. I went on the ground under the chairs looking for it. It was at that time that she came up to me as I’m CLEARLY on all 4s with a flashlight and said “I need to get by”. I said one moment please I’m getting something from under the seat (while my head was literally under the seat). Her reply was “no you need to move now” and proceeded to almost push me out of the way. I looked up and all I saw was her toes under my eyes. When I looked in front of me, her private parts were inches away from my face. I then made a comment “you couldn’t waited 2 seconds?” and her response was, “no I need to use the bathroom”. I understand that and would never want to be the reason someone couldn’t get to the bathroom but I was under the seat. She could’ve gone around the other way instead of harassing me, basically placing her private parts on my head and borderline pushing me out of the way. You don’t pay (especially this much) for this deplorable experience. This was by far the worst experience I have ever had on American. I will be absolutely thinking twice and thrice about flying American Airlines again. I would rather pay more to fly delta because at least I know their WiFi will work and their flight attendants won’t have a terrible attitude for no reason, nor will they act the way this woman did. Unacceptable.

Liked - nothing. Disliked - delayed 35+ min sitting on the plane. Caused me to miss my connection in Charlotte. American Airlines is the worst US Air Carrier company with atrocious customer service.

Worst situation ever! I booked my tickets for this trip on Alaska Airlines. I guess AA is a partner and we flew nonstop from Eugene to PHX on an AA jet. I had to pay for luggage from PHX to EUG. And this was an Alaska Airlines reservation paid for with Alaska airlines credit card! Got to the PHX airport and was not able to check bags because of some weird issue with the AA software. My reservation had to be the-entered by the agent. I will never pick another American Airlines flight on the Alaska Airlines website. While on vacation, I tried to upgrade our seats for the trip home. The request just buffered and never went through. I tried four times and was charged four times on my credit card. The card was charged but the seats were never changed. What a wreck!

Left from gate 30 minutes before flight. Never been late to a flight ever. It says 15 minutes before explicitly on the ticket.
