with above mentioned resevertions we booked flights with Aero Mexico Not a happy customer. We upgraded to business class on 2 of the flights Amsterdam to Mexico City and Mexico City to Amsterdam. The other 2 flights were premium economy. With reservation JUDDVT I booked the wrong flight from Cancun to Mexico City s with reservation WHDIYR I booked a new flight which was not found at check-in, so we ended up flying economy. At the end of the First flight from Amsterdam to Mexico city I asked a steward a question about the wheelchair assitence i resquested. I got an really rude answer, not 1 time, but 3 times. When we flew back we wanted to go to the lounge in Mexico city, when we arrived there a gave our boarding passes, we were told in the most rude way that we were not allowed because we upgraded through a promotion, which we did not. We were even accused of trying to sneak in, we ended up paying for it, which was a huge mistake, because it is not what was promised. We are very disapointed with aero mexico and will never fly this again. By the way in Amsterdam we had no trouble getting in to the lounge. My email is [protected]@msn.com Kind regards.
