flight was delayed 4+ hours. there was really no understanding of why? weather? the last hour of delay was post boarding. pilot seat was broken. was that the real reason? nonetheless, long day of inconveniences.

During the flight, the only refreshments provided were crackers and soft drinks; no substantial food was offered despite the international route. Furthermore, our initial flight was delayed, causing us to miss the connecting flight in Atlanta. The airline did not hold the connection, and we were informed that the next available flight is not for another 24 hours. While I am aware of alternative options via JetBlue, they operate out of JFK, which is not a viable solution for us as a resident of New Jersey.

Arlene was a great flight attendant. I also liked how one of the other flight attendants gave us a heads up about snacks and asked everyone to remove their headphones when it was their turn to order. Good idea.

I was happy that I was able to get a last minute flight but unfortunately my seat was a middle seat. Even with Delta Comfort I wasn't comfortable

bulkhead seat had very little legroom - even in bsiness class.

The seats weren’t reclining even though it wasn’t as exit seat

It was good because we traveled without luggage, carry on only.

Flight was delayed. Had to get rebooked. Diamond medallion but stuck in a crappy seat. Rebooked flight then got delayed again. Then when we finally boarded, we waited another hour for a new crew. Then landed in JFK and sat for another 40 minutes waiting for a crew to come to the gate to be able to deplane. Hot mess all around, which unfortunately is becoming the norm for Delta

Our flight to Zurich was delayed by almost 3 hours, so we missed our next flight. There was no indication it would be delayed this much. We were told the gate had changed and then it apparently took over 2 hours to load the "catering" on the plane. We were not compensated in any way for the trouble.

the entertainment for the flight from DAL-LGA was not available.

Awful. Delayed flights, missed connection to Toronto. Hotel vouchers were for already booked hotels x3. Giant waste of my time

The entertainment is a bit limited, it would be better if they added some games to play besides the movies and tv shows. But the seats are comfortable and the crew is polite

The pilot had to extend the flight time from san antonio to Houston to burn off fuel. This caused a lot of unnecessary stress since we had a tight connection to Aruba. And with no other flights going to Aruba we were worried about spending a night in Houston. We had to to run to our connection because of the flight crews mistake. Not happy.

Fine. The issues I had were associated with luggage being delayed from Turkey to Tanzania

Do not like the size of the overhead bin. I think staff should monitor the size of suitcases that are being carried on by passengers to ensure they meet the size requirement.

Flight was good and crew was super polite. However, there were around 5 kids screaming the WHOLE 2 hours. I understand kids have to come but parents need to do something to control their children. They make the experience terrible, especially after finishing 16 hour shifts at the hospital I needed some sleep, which I did not get.

Gate agent did not hold flight for connection, provided no assistance to get new flight

Nothing they cancelled my connection and couldn't get me on a flight for 3 more days

Plane was older and terribly uncomfortable but the leg room was good!

The flight spent 2 hours on taxi and then would not allow people off the plane which made me miss my connecting flight . Terrible customer service and poor organization from United

This flight moved Gates several times in a short time period, from B to C, which required a substantial walk or rail ride. Then the flight was delayed more than 2 hours and the food was subpar compared to other flights.

Flight was delayed 5 hours. Initial reason for delay was 'maintenance' - which makes sense. Then, the additional 2 hours continued to say it was maintenance - when I know EWR had a 2 hour delay. AA did not say that. Additionally, when boarding, there was only one agent at the counter for a long time - until another came to help. After boarding, we had to wait another 45 minutes due to 'no catering'. So while we waited for catering, AA continued to board additional passengers - which seemed odd - and raised questions about what really was going on. I sat in First Class. During the flight, the flight crew allowed a significant number of non-First Class passengers to use the front bathroom - which created a very crowded environment in First Class which was uncomfortable. This also delayed First Class passengers from using the bathroom. Overall, horrible experience.

Returned home with a blood clot from flight homes and the uncomfortable aircraft I was on.

It was really a terrific experience both going and returning on AA. Staff and crew were professional.

Seat was VERY uncomfortable. Flight was delayed and then boarded slowly. The crew was super helpful with boarding and supporting maximizing the luggage in the overhead.

Absolutely terrible. Would never fly American again. 2 deplaned incidents and delayed by close to 24 hours. $12 meal voucher for first class passengers was an insult to the injury. Pathetic.

The crew was excellent and overall the flight was good. No complaints.

Delayed, no updates, had a rewards number but was not working

I'm not a valued flyer so I'm always in the last group to board...that sucks, always

Flight was delayed. Paid $250 per person to upgrade to first class. Seats didn’t even come with a screen for entertainment, didn’t get a blanket or pillow or anything, the poor hostesses looked like they were scrambling the entire time because there wasn’t enough of them. My premium economy seat on my previous flight was a better deal. Once at the airport (landed at midnight after 26 hours of travel) our bags didn’t arrive until after 2 AM. We kept asking the AA crew where our bags were and they told us for two hours “they should be coming out now” and offered little to no help in terms of what we could do to get our bags or where our bags were. They even disappeared into a back room for a solid 15-20 minutes when they got tired of not helping the dozen or so passengers waiting for two hours for their bags.
