Advertised fruit trays with cheese, but only snacks handed out!

The plant way delayed departing by 3 hours. It was an old airplane with broken seats and armrests. The bathroom made a hollering sound. A really crappy flight experience and travel day all around.

Premium economy is like the forgotten class. Aside from meal service never saw a flight attendant. Any additional beverages required going to the very back of the plane to request and there was rarely an attendant there. Seat leg / foot rest hardly elevates and not well suite for someone under 5’6. Bulky armrests

Flight delays both to Detroits and return flight . The flight to Detroit was associated with mechanical difficulty

Flight was operated by Virgin Atlantic and it was up to their usual high standard. Minor grips about some issues, but they are really first world issues and as a whole, was an excellent flight.

I am extremely disappointed that delta internal pilot manuals now refer to the Gulf of Mexico as the “gulf of America”. You can bow down to the Orange turd on your own. I will never fly delta again

Delta One upgrade it would have been great if my tray extended (it was jammed and wouldn’t pull out), seatbelt had too much slack & my little cabin door didn’t close properly

I paid for a business class ticket on Delta. It was sourced to Virgin Atlantic. They changed out the aircraft which had fewer upper class tickets. Even though I'd checked into the lounge, was receiving alerts via kayak about the delay and changes; no one informed me that the seat would be changed - until I attempted to board and was told that I would have an economy seat or they could search to put me on another airline. Even the flight crew were informed of this change (10 passengers were bumped out of Upper Class) around 2 pm (1400) time. Hours would have helped to consider alternatives instead of making a last minute change. There needs to be compensation from both Delta and Virgin given this change in service/experience.

Wasn't a Delta issue I don't think, but seems there was a Delta flight at each of the 2 Dallas airports at the same exact time, both to Atlanta. I was evidently booked on the one at Love Airport, but the Carey transport shuttle took me to DFW instead and I ended up missing the flight by just a few minutes. Was able to book a Southwest flight from Love Airport, but was a big loss of time and an inconvenience.

Every single flight that we got on was delayed by several hours or more. I honestly didn’t think we would get out of Atlanta because our flight was supposed to leave at 7:59 and it kept getting kicked back further and further. Delta stands for Don’t Ever Leave The Airport!

The flight was delayed for 1:30 hours for maintenance issues. They should give more information about connecting flights. For a Business Cabin the Crew was mediocre.

The food is terrible. The same pasta or chicken with bad taste and presentation

It was probably one of the worst flights I’ve been on. The restrooms were never cleaned or stocked. The food was very subpar, and i usually enjoy airline food, so I was disappointed. It was just all around a bad experience. The only saving grace was the flight attendants.

The only downside was my cell phone charger wouldn’t work in the charging port but everyone else’s would work in them all. My cell phone cable works fine in my hotel room in Frankfurt.

Great crew, excellent landing, good food. Over all great experience. Thank you!

One bag is incorrect and not acceptable for an international flight. The food was not just good. I won't fly with them again.

Not pleasant trip cross country when the entertainment and WiFi system not working. No entertainment for entirety of route. Staff was rather nonchalant in that they dismissed the problem due to age of plane. It would have been nice to know this up front so I could have come prepared to read or download movies before boarding Coincidentally or not, there was a similar issue with the entertainment system on my previous flight I took on my fist leg of the trip. There are no seat TVs, so you must rely on the app when it works. United can do better. Also, what use it it to pay for boarding group 2 when half of the passengers are in the same line as you?

Crew was dismissive. Snacks and refills not offered. Poor business class experience. Bed not comfortable compared to Emirates or BA.

Flight was delayed for 5 hours because crew didn’t have enough time to rest - this seems like it could have been avoided with better scheduling. Food was not good.

IAD with the archaic people movers is just a place to be avoided.

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

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

It was good in general. The Crew during the flight were very nice at all times.

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

the guy in front of me put his seat back immediately...and then left it back including thru landing and taxiing to the runway. attendants did not check/ask him to put it up for landing.

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.
