The gentleman at the gate I think his name is RIE was exceptional

With Aeromexico it ended up good but with Delta it was bad because we did everything through Delta... Showed up at the Delta terminal... It was the wrong place! Nothing ever told us to go to the Aeromexico terminal. It said "in partnership with Aeromexico" but I was never instructed to check in with them or go to their terminal. We had to haul @$$ running through the airport and almost didn't make it thanks to this poor communication. 👎🏽

Excellent!!! Aeromexico is a great airline. What was not that good is the service provided by Kayak. It is never clear and not easy to manage.

This flight was no comparison to our prior flight. I'm thinking it all has to do with the age of the aircraft.

2 of the seats in row 31 the entertainment system was not working, and one seat the tray table did not go all the way down. Flight arrived early and departed on time which was great.

Waited at the usual crowded gate at DCA where one ends up standing up because there aren't enough seats.

Delayed take-off. Very small plane so very scary with lots of bumps during the flight. Would never fly Delta on short flights in small 80 seaters plane again! Felt relieved when landed.

Inexpensive, got an exit row aisle aeat with no middle passenger, bought a great breakfast sandwich, flight comfortable & arrived ahead of schedule.

I wouldn't say I liked being forced to check my small roller bag at the gate; too many people had bags and were in a higher boarding group.

715PM departure was 2.5 hours late. Received hotel & food voucher but after we already booked a room. Entire team just seemed like they were 2-3 steps behind in execution, and notifcations.

Staff could’ve been a little more cordial. The men were much more friendlier than the women. My daughter and I also missed the 2nd to last meal as we were sleeping but that is on us.

Like: departed and arrived on time. Unlike: Food options for purchase allways bad, 1 of 2 of the crew members not very friendly at all. Seats and leg room aweful. At this point I am thinking on switching to AA.

Over 5 hour delay with minimal updates or ability to standby for alternative flights. During boarding and 1 hr+ wait for takeoff, seats were drenched w water from air conditioning condensation and always leftover crumbs on carpet and seats

Our flight was canceled same day and we were never informed. Had to pay more and worse seating on another airline.

Did not like that we couldn't complete check in on-line without providing pictures of our passports. Worry about identity theft. We had no delays and boarding was handled In an efficient manner.

Excellent! I got to Munich and was transferred to my Lufthansa flight quickly, in 15 to 20 minutes, so I did not miss my flight. However, I had checked my overhead bag at the boarding gate in Tampa. That got to Tunis the next day. That is to be expected.

WiFi didn’t exist , seats were super cramped, lights stayed on near my seat for a long time while others were dimmed, the food/trash/drink cart hit my shoulder at least a couple of times while moving, food options were down to just one option by the time it got to my row, the utensils were garbage (knife bent at a couple of places by the time I was done eating) the spoon was very flimsy plastic

Vegetarian selection could be better. Bread was too hard to chew.

Staff was rude. Didn’t give water for 2 hours. Worst service

I bought internet for the flight. Don’t waste your money. I wasn’t able to download a 1 Mb file from Google Docs during a 3-4 hr period. You can only use WhatsApp and email if you are willing to wait.

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

Lousy No wheelchair. As normal at Atlanta Cheap airline Cheap aero plane. - Neither entertainment nor food on a 5 hour saga

This is not a low cost airline. Stop acting like o e.

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

Some entertainment and food/snack service would have been nice

All the pessengers should be wait in a line útil the creo and piloto are arrived.

Planes seat could be bigger very uncomfortable for tall humans.

1 hour waiting for suitcases to come out traveling in business class and food in business class is a sandwich? Avoid Aeromexico .

No space reserved for anyone who didn’t have underseat in front of them. Made it inconvenient to get the backs secured. No inflight entertainment in the 190. Bring your own! Food was excellent and we were surprised to get a full breakfast.

The seats were extremely cramped, with very little legroom or personal space. There was no room left in the overhead bins for a backpack, and the space under the seat in front was so limited that I could barely fit my bag underneath. Overall, the seating arrangement felt very uncomfortable and overcrowded.

As always, most AA flights that we fly are almost ALWAYS delayed and that too multiple times. Very frustrating

The small flights with Valet Luggage has a poor service

Overall a good experience, however Wifi was not working on the flight.

THe flight was an hour late. You got us on the plan and we sat on the ground for 45 minutes with no information from the pilot whatsoever. Worst flight this year.

Going non stop to lax like I paid for. Not stopping in MCI for gas. Too long of delays

Human interaction. Thought there would be more service-even a smile would have been nice.

Incoming flight was delayed, delaying boarding. It then took 30 mins to take off. Took 20 mins to get to a gate because they changed the gate last minute, crew weren’t ready so there was no one staffed to work the jet bridge. Boarding was so disorganized as is usual with American because everyone just stands around the gate regardless of boarding group.

Delays with no explanation. It could have been handled better.

Flight delay for mechanical. Inbound arrived on time. No one said why mechanical delay.
