For the expense of first class, the seats could have been nicer and higher tier snacks would have been nice.

For the expense of first class, the seats could have been nicer and higher tier snacks would have been nice.

They delayed the flight 3 hours because it wasn't full they moved us to 5 different gates probably the worst airline ever not even spirit is this bad.

Packed flight, which makes it tough on crew and boarding staff (and the customers of course). But this was great boarding, clear instructions, etc. Traveling on the weekends are always fraught with danger as you have families and less frequent flyers thus more confusion. But this flight went as planned.

Boarded early, left early, arrived 40 mins early! A win win for me!

I felt scammed. The priced advertised was different than what I paid. I paid the whole some online. I then got a call 20 minutes later saying I need to paid 70 more person. She said the price online is not the guaranteed price.

We had a delay, but thankfully I made it to my connection. Overall it went smooth

Left an hour and a half after the listed time. Up side was it had TV screens on the seat.

It's a long flight and I would have liked better snacks between lunch and the arrival meal. It's fine to have fruit and nuts but I really don't like ramen because it's salty junk soup. I'd suggest sandwiches. They're not expensive nor are they hard to store for a long flight. The FA's had a couple of big services and they were super busy preparing, executing and then cleaning up. Then they disappeared.

Great flight. Got to watch a movie. Smooth flight and early arrival at ORD.

Poor and identical to the first two legs, except for the crew who were patient, professional and of pleasant and jovial disposition!

Forced to check bags. Crew uninterested in collecting trash. Unclean seats.

There's nothing I liked about it. For first off I scheduled this trip two weeks in advance then they delayed my flight which messed up my whole trip. So I scheduled it for the following weekend thinking there won't be a delay and guess what as soon as I got to the airport we said in the airplane on the tarmac for an hour and a half. Not only was it delayed I missed my connecting flight meaning I had to stay the night at Dallas-Fort Worth airport sleeping on the floor. I will tell you this I will never fly American airlines ever again I have had nothing but horrible experience with them and I just throw money at them

They changed my seat from one that I had paid for as an upgrade to a regular seat at the last minute.

The seat could not recline. This was not indicated as such when I paid for the seat. So itvwad not the most comfortable ride. At boarding, the staff could have more pleasant even though it may be an intense time.

WiFi was not working from pos to Mia…. As well as they rushed us to the gate as if the flight was already here and leaving shortly when the plane never even arrived and took off until the scheduled time so then why rush us to the gate and have us thinking we will miss our flight.

Very aggressive and unhelpful ground crew. Wanted to check my hand luggage for 3 flights. I had lots of delicate items and computer equipment. So the silly lady wanted to rebook 3 international flights because of a carry on. What nonsense. The baggage handler suggested I put it under my seat - so I did. And this was during the rebooking chaos of the Microsoft crash. She was the most arrogant annoying and aggressive ground staff member I’ve met in 20yrs. (AA flight out of Houston).

Left from gate 30 minutes before flight. Never been late to a flight ever. It says 15 minutes before explicitly on the ticket.

Was as expected. Good leg room on planes - much appreciated.

I know that there is nothing than can be done about rude customers. I did find a couple of them were very rude and inconsiderate In my case the guy who was sitting in the same row as I was in, was trying to watch a movie with no headphones, a crew member did ask him to turn it down or off (thumbs up for that.) Another thing, as we were about to land another young man must have taken his phone off airplane mode was talking with his friends and using fowl language which I found inappropriate to the ppl who were sitting in the same row as him and other ppl around him. I understand how no one wanted to address this person and not get involved. We all just wanted to get home safely with out any incident.

The food service was limited and not good. For a seven hour flight they could do better.
