Miserable. This entire round trip was miserable. I booked evening flights to and from Detroit on consecutive days that should have had me at my destination by 10:30. Instead I arrived after 3am on my flight to Detroit and after midnight on my return. Multiple unforced errors like awaiting bags to get put on the plane for almost an hour in Detroit and a 20 minute delay to pull up to the gate in Atlanta has me rethinking my assumption that delta is the best and most reliable airline

Perhaps when you’re sitting in 1st class and the crew closes the bathroom for the pilots, there could be a notification other than holding your hands up as a blockade when you get there and you’re told the restrooms are closed please turn around … especially at night when visibility is poor and you’re met by a flight attendants with their arms up

First class is comfortable. Enjoyed a movie and was able to relax compared to coach.

Loved flying First Class. Very comfortable. The seat was amazing. Enjoyed a movie and was able to relax so much better than in coach.

We landed and sat on the tarmac for 45 minutes because they only have one gate at the airport and there was another plane running late so we had to wait

The WiFi was not working. That made for a long flight.

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. 👎🏽

Absolutely no communication on why there's a delay and multiple flight time reschedules. I would have canceled the flight and drove back home if I known it was going to be rescheduled 3 or 4 times.

Another late night flight and MORE men belligerently drinking and yelling. I had to move from first to economy because they were so obnoxious and disruptive. Crazy to go from a cozy chair to cardboard when you were supposed to be in first. Delta allows was too much drinking which leads to belligerent behavior.

I was in first class and literally the men behind me were so aggressively loud I moved myself to economy. This has become so common on Delta - people using audio without headphones, and men on 12am / late night flights drinking and yelling to talk to each other which prevents anyone around them from resting. Pretty crazy to have to move from first to economy (poorer service, less comfort...). Wild wild. Looking into other airlines.

The business steward was absolutely amazing! Smiles and kindness! Wish all AA flights are like this one!

As a first class customer, there was no power the entire flight which limited my ability to work. I find this unacceptable. The first 11 rows on the left side of the plan were out. I was only offered the option to charge my phone which was not the issue because my laptop was out of power. I asked if there was anything that can be done for me, and the answer was, "no". I was not offered any type of compensation for this AA problem which caused me unnecessary stress due to inability to address business issues on an already challenging travel day. Flight attendants tried to reset the power once but that was the extent of their support. Very disappointing for the lack of expected services on a flight. Please contact me with customer focused response to this complaint.

Not really sure I enjoyed the flight at all. The flight attendants seemed a little tired and rude at times. The snacks were lacking in taste and sustenance. The flight was incredibly turbulent for three plus hours and the pilot had to do a second pass to land at our final destination because he was coming in so fast. He must have taken a short cut and because of it we had to suffer the violent turbulence and the dropping down. It had to be one of if not the worse flights I have ever been on and have traveled vastly all over the world.

Delay after delay with little communication then AA lost my luggage and at airport would not assist just said scan this QR code to track your luggage and submit a claim. However QR code provided did not work so have to go back to airport

After changing the departure gate 5 times making us mo e from one side of the airport to the other and then back the flight was delayed nearly 2 hours. The male flight attendant had a bad attitude with the guest being condescending, disrespectful with people who were already on edge.

Easy boarding. Rows are smaller but that may be an older and bigger me now :)

It would have been nice if American tried to care.

American Airlines did everything they could with the high Spring Break crowd. I was frustrated to be changed from 1st class to a middle seat at the back of the plane. This has happened before, not sure booking 1st class and paying the extra actually works.

I booked 1st class, my flights were changed and I was sitting in the middle at the back of the plane. A far cry from the 1st class I purchased for my flights. I am grateful I arrived on time.

Aging planer and NO wifi on a 14 hour day flight. Unless you are retired or don't need to work or be in touch with the world... The lack of Wifif really ruined the flight. And the old plane - really showing it's age, wasn't great
