It was last minute due to weather - considering - it was amazing! Good smiles, friendly staff and they were making sure we knew what was going on when and where.

It was last minute due to weather - considering - it was amazing! Good smiles, friendly staff and they were making sure we knew what was going on when and where.

delta last minute gave me a boarding pass for a different flight with no confirmation that they were changing it

The flight was comfortable and uneventful, which is what I desire

The service from the flight attendants were of supreme quality. They greeted and treated everyone with a wide smile. This is totally absent nowadays. Kudos to them!!!!

Excellent flight and got us around tough weather. Only issue was seat TV did not work and crew tried to reboot.

Very large passenger too space from my own seat. Arm board couldn’t be lowered because of his size. It wads very uncomfortable trip, as the flight was full couldn’t move anywhere having back pain because of the position in which I was the entire flight.

was sitting in the jet bridge for 10 minutes in -20 degree weather waiting for my bag

Outdated equipment in disrepair, wifi inoperable. Broken seats, taped air vents, generally poor condition, the 717 showed its age and lack of upkeep.

My flight out of Baton Rouge to Atlanta was delayed by a half hour. This got us into Atlanta airport 30 minutes late. I ran through the airport to get to my connecting flight. As I approached the boarding gate, I saw the boarding door was still open and a passenger was being checked in. But when I got to the gate, the boarding agent told me they had already given away my seat and there were no empty seats on that flight. So I had to take a later flight. That has never happened to me before. Very frustrating.

Connection through Atlanta was difficult. Mechanical issue on plane caused a two hour delay. New gate was a mile away.

Really nice, all good, nice crew and all on time

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.

My flight to London from Philadelphia was cancelled due to weather.

This flight captain and crew were amazing, started ahead of time of departure and reached 30 mins before arrival time. Amazing!

Long delays, lack of information about the status of the flight. The flight was delayed 4 times.

Everything about the flight was lovely. My only suggestion would be to offer a few more options of tv series from Apple TV or HBO.

Flight was late and boarding was confusing because gate changed and I didn’t get a notification

Not comparable to Qatar Airways services on flights to Doha. Flight attendants provided basic services; I was never recognized by name or as an Executive Platinum member. Restrooms were not kept clean during the flight.

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.
