The staff and the boarding procedure were all amazing . The one flight was not equipped with WIFI which now adays seems odd. All in all the experience was good

Passengers need to check in big baggage instead of bringing on the plane. That cause inconvenience for everyone. Otherwise flight was good.

Perfect flight both ways. On time, courteous staff, plane comfortable and cool. Best domestic flights I’ve had in awhile.

The food was terrible especially for a 15 hour international flight. The crew was unpleasant as well.

Really low quality food especially for an international flight. The crew also was surprisingly unpleasant except couple of ladies. I know we were not in first class but that’s no reason to treat customers as less.

Flight delayed for two and half hours and then canceled altogether due to mechanical issues. No mechanic onsite to fix so had to send one from LAX.

Quick check in. Everything went smooth. I don't know what can be done about airline food.

Crew was good. The reservation got mixed up and they didn't have my TSA number. I am also a Silver Medallion and wasn't able to use Sky Priority.

Delta made it easy, comfortable and timely. The crew was fantastic.

This route with Delta always has delays or is cancelled. Aircrafts seem smaller and older. I fly Delta quite a bit - haven’t had issues with the international flights. But this route has always been the troublesome one

Aeroméxico cancelled my ticket without advice AND It make a last minute mess in my intinerary, no solving my situation, bad advice and bad customer service

The ground staff were not as friendly and nice to the passengers as the air crew. Flight attendants, cockpit crew were great and very nice to everyone on board.

My flight was delayed, then I got transferred to a new flight that was also delayed- which wasn’t Aeromexico’s fault, it was because of weather conditions. Most of the crew was very nice and patient, except for one or two flight attendants who were rude. The entertainment wasn’t on, so all the screens were off.

My wife's entertainment system did not work. Payed for flight upgrade but did not receive advertised "free WiFi".

Annoying that we had to go to departures and get boarding passes. Should allow us to be booked all the way through, this is the only airline i have this problem with in MEX. Late boarding and take off

Lousy No wheelchair. As normal at Atlanta Cheap airline Cheap aero plane. - Neither entertainment nor food on a 5 hour saga

The airplane was an old airplane, seats were very uncomfortable and very little space, they changed my seat and that was no option to get back into my seat even when I was traveling a senior who required assistance.

This is not a low cost airline. Stop acting like o e.

Aeromexico crew made me check my hand luggage in the door of the plane. As soon as I reach Mexico City, I notice that my luggage was opened and 8 games of Nintendo Switch were stolen (700 dllrs value aprox) (the console was there) but the games were stolen. I am very dissapointed of Aeromexico and all the crew. Instead of being a good trip, It was a sad trip

Ok. But we arrived to a remote terminal which meant that a bus had to take us to the terminal building

Once we got in the air the pilot made up some of the time of the delay. So that was really nice.

We had a layover from YVR to Denver. We bought 4 bottles of Absolut Vodka at the YVR Duty Free for $116.20, after going through security and American Customs Pre Clearance at YVR, Vancouver. When we landed in Denver, United put us behind the American Customs as well as TSA again for some reason. We were forced to go through American Customs and TSA again. TSA confiscated our rightfully owned Duty Free Absolut Vodka bottles. Because United incorrectly forced our flight behind American border and TSA again, we missed the connecting flight. After United put us on a later flight, we eventually arrived in Chicago very late, with hardly any sleep. I am looking for compensation from United for our incorrectly confiscated Absolut Vodka bottles worth $116.20, as well as compensation for incorrectly putting us behind American Customs and TSA again, causing us to miss our connecting flight, making us arrive extremely late in Chicago.

Excellent flight. Boarding was efficient and departure was on time. Smooth flight with on time arrival. Deplaning was also efficient.

It was delayed instead of departing at 9:20pm, we departed at 11pm… putting us in Columbus after 2am! It was awful. Had I known about the delay, I could have spent some time in the United Lounge… I was starving because I started my journey in Budapest… so I was exhausted and hungry. Plus I had to make new arrangements to be picked up at the airport in Columbus, instead of midnight it was 2:30 am after getting luggage and out of airport. Not feasible. I would have just stayed in Chicago for the night and gotten a morning flight.

It was great, I’m very grateful for the pilots and crew flight attendants for everything.

Evidently, my seat had the only broken TV. I couldn’t plug it in, get it to come on, or watch anything, and of course, no one could fix it while we were on the plane. The service was good and the boarding was quick

The boarding of took of late.The presentation of the food was horrable as was the tast of the food was cold and tastless.

Delay and keep changing gates. I have to run around from B to C then to E.

I was charged for my daughters bag when I am supposed to receive two free checked bags with my United Explorer card.

The schedule to Moline changed 5 times. The gate changed 6 times. That is a pathetic way to run an airline. No wonder that no one in our company flies on United Express to or from Moline. Changes happen most of the time. I learned my lesson on this trip…never again!

Lost luggage stuck no clothes and no word after 2 days leaving on cruise no stuff or clothes

3 hour weather delay followed by 1 hour (and counting) maintenance delay. UGH!

After we'd boarded , they canceled the flight. The crew didn't even know , we just all received text messages. Then after they deplaned us , AA was just like "too bad, go F your self, we sure ain't gonna help you"

After a two hour delay, my flight was CANCELLED! No pilot available. Such BS.

Amazing food, great staff, with one noticable detail missing ...but no seat entertainment in any of aircraft ...I am not a fan

I wish American Airlines would change the airline industry by loading the plane back to front instead of front to back. Planes would board so much more smoothly and quickly.

I have long legs, my foot was out in the aisle and when a flight attendant came walking by and I didn't notice, instead of saying "excuse me" or anything like that, she kicked my foot. Extremely rude

Excellent! The gate agents were kind enough to rebook me on an earlier flight saving me from a 6 hour layover. Even my luggage made it despite the fact that the connection was technically too narrow. The flight itself was very comfortable, roomy, and clean. Plenty of space for my carryon items with plugs to charge my phone. After a long international flight of 14 hours, this was an excellent way to end my travels!

Great experience. Flight boarded easily. Departed early. Smooth flight. Great arrival in DC--almost no taxing! Almost direct to gate from runway. Crew was terrific. Same cookies and beverages in main cabin. I did not use the entertainment system on this flight.

This particular flight wasn't very full at the back, so there were three seats available for spreading out and getting relatively comfortable
