Lady Pilot was perfect in every way wheels up to wheels down communication, professionalism, excellent on time departure and on time arrival, excellent communication! Fantastic job with Superb attitude!!

The food is terrible. The staff is wonderful. Comfort is good.

Left on time, a bit delayed due to headwinds most of the trip.

I fly Delta all the time, have Platinum Medallion status. But this route seems to have major problems with delays and seems to never leave on time! Have only taken it twice in the last two weeks, and each time it had delays of more than 1 hour... very disappointed!!!!

Getting to the flight was arduous and lengthy. The flight itself was good but the food option wasn’t a good selection. I need to do a Kosher option on my return. Flight crew were nice

Good seats in Main cabin, excellent service and excellent landing

My flight was cancelled with no explanation after I had already cleared security. I was given 4 options to rebook, only one being non-stop like I had paid for. I grabbed it. It was 4 plus hours later and then took off even later. Biggest complaint is that I booked early and had an aisle seat. They gave me a "window" seat in front of the exit row, so the seat did not decline. I weigh all of 103 #s and it was tight for me! For what I paid, I feel I was kind of ripped off. I think they should have given me the empty comfort seat for the inconvenience. There was no apology nor any explanation as to why the flight was cancelled. My guess is it benefitted Delta in some way.

Very smooth, on-time, and pleasantly uneventful flight. The team at the gate and on board were professional and genuinely courteous. The pilot kept us well updated throughout, and both takeoff and landing were steady and enjoyable without any drama. Just a good, solid flight. Thank you! 💗

Staff was exceptional! Everyone was kind, professional and friendly making the trip very pleasant. Thank you!

No lunch on a x-country flight scheduled for 10:50 am departure, arrived 5+ hrs later. That requires a black box label before you pay for the tickets. Worst, when I checked in online, it's specifically said that lunch was served on his flight for economy Plus passengers.

Unfortunately I had an awful boarding experience. Our first flight with Aeromexico was fine and landed on time however it couldn’t find a gate and we were late which made us lose our connecting flight with Aeromexico. The staff handled it horribly when we explained our situation and would not led us board when we missed the boarding time by a couple minutes. The staff were extremely rude and did not attempt to even help us. Because of this incident, my husband and I missed a full day of work which negatively impacted our salary which we need. Please compensate us for the work that we missed.

It was OK. The flight is pretty long for the airlines to only offer a simple sandwich on business class. The entertainment is similar to that on other Skyteam members. Ultimately the airline lost my bag and didn’t deliver it to me until the next day after a lengthy lost baggage report.

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.

Delays to take off and to leave the plane after landing added a lot of time to this flight.

The Phildalphia to Allentown portion was a BUS, not a plane. All was as expected.

Excellent - explanations were clear staff was nice and flight was comfortable

Airport in MXP is crazy. Get there at least 2 hours before flight.

Flight was delayed not sure why no explanation given and no apologies either. Otherwise the flight was fine

Did not get the seat I selected and paid for.

The flight was canceled 3 hours after original take off time

Plane was delayed for 6 hours, at first by weather, which is understandable, but was further delayed with NO given reason for 2 1/2 hours more. We had no clue when we were going to depart actually until they opened the ramp. VERY POOR to ZERO COMMUNICATION!!!

Flight was delayed and after being in the airport for like seven hours, it was canceled.

Flight delays numerous times. Everytime we would get close to boarding it would be delayed again. Strung along the entire time.
