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

Old aircraft the audio of the entertainment dosent work Dirty seats

The plane was so outdated, that it made it uncomfortable. The temperature was hot during the whole flight

Happy attentive flight crew. All in all good flight the night flight works well. Getting into Mexico City early so you don't get caught up it all the immigration and custom ques, additionally, this helps when exiting the airport and crossing the city to your final destination. All works very well and would do it again
