I took seat 15A in anticipation of window seat, there is no window.

I took seat 15A in anticipation of window seat, there is no window.

The first class flight attendant was awful to everyone. Very rude; no customer service. She should not be working in first class.

Snacks and included beverages were appreciated. Boarding went smoothly. Plenty of overhead bin space. Seats get very uncomfortable after a couple of hours. After waiting 10 painful minutes for my walker, a very nice Delta guest agent pushed me in a wheelchair to the gate. It was finally delivered to me after another 15 minutes . Our checked bag was on the carousel long b4 I was able to retrieve it. Fortunately it was still there but somewhere along the way the straps we used to secure it were removed and and were not reattached. Wish I had made note of the agents name.

It was fine. 55 minute flight. No snacks or beverage service offered. Boarding went smoothly and my walker was waiting for me on the jet way.

Smaller plane for a longer flight than my first one. Doesn’t make sense.

The cabin temperature was nice and cool. The wifi was not working.

Flight late, the waited for a long time for “personal” to arrive at gate to dock the plane in Rochester. So annoying. This flight was expected, why aren’t personel available for the jet bridge?

As previously noted, this flight was great: departure was timely, the crew was friendly and attentive, and wifi connectivity was seamless. In particular, I appreciated that the flight attendant just told me to stow the laptop right before takeoff/landing, and trusted me to do so (which I did!).

Kayak botched up the booking, i had to call delta and fix. In the process Delta failed to honor my comfort plus seat assignment that i had previously.

Entertainment is ok! Boarding and seat with zone is terrible. I paid for the seats but you didn’t give me what I paid for which is exit isles.

All went very well. We used the AIFI Airport, such a lovely facility. Definitely needs better transportation options to get there.

Both ground crew and flight crew were rude, and did not provide any level of service. They made it very difficult as we were traveling with a passenger the required assistance.

From the check-in, to the flight, and arriving, everything went very smoothly. Unfortunately, when I received my baggage it was severely damaged. I have a hard shelled suitcase and it was completely smashed it. I’m not sure how this could happened but I am extremely disappointed that my belongings were damaged beyond repair and continued use.

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.

Good, the flight from Miami to Mexico City was better than Mexico City to Miami

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

Flight was on time, good service, but there was no free WiFi, even for first class passengers

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.
