Both legs on the way were smaller planes, each had a mechanical issue causing a delay

Delayed flight. Dirty seats, dirty seat belts with food stuck on it from previous passengers maybe. No one cleaned the seats or flight.

No headphones, forced to sit in another seat that I did not book, had to check my carry on when I boarded the plane I saw backpacks and other non carry on items stuffed in the carry on holder! Horrible experience Wi-Fi did not work either

There was no food, so :( to that one. The flight was delayed by 3 hours. Not Delta's fault. Not the crew's fault. Considering how tired all us passengers were, everything went surprisingly well. The flight crew were very helpful, friendly, and professional. I always fly Delta.

Terrible. Waited on runway for 1+ hour after landing and then was brought to wrong terminal

Some of the passengers are coming on board with luggage so overstuffed and/or too large that have no business going into the overhead bins.

Crew was great. Near on time departure and early arrival. Snacks are always meh. Not a fan of the "pay for everything including miles " proposal unless base flight rate going to be 100 bucks.

We had a lot of really rough weather but that was not Delta's fault. Pilot was amazing.

The boarding process needs to be refined. Sometimes the gate crew call out the boarding zone, and then flip to the monitor to show which zones are boarding. So unless everyone is gathered around to see the monitor there is usually confusion as wi which zones are boarding.

The young man who was our flight attendant in first class was lazy and did not do his job well at all. Never offered drinks upon boarding - actually I take that back... said "are you okay with water" as if I do not want to get you anything else, only passed the snacks around once, got my drink order wrong and then never offered a second round of drinks. He was the worst I have ever seen on Delta and we fly a lot.

Did not like the check in guy quibbling over a couple pounds at the luggage weigh in

This is related to my second leg of the flight, from Washington DC to SFO. I understand things happen, but I got home at 3 am for a 12:59 am landing. I live 10 min from the airport. Bridge breaks when a few rows of the plane are off? Maintenance didn’t catch that?

WiFi was slow as compared to trip down. Maybe because it was a night flight and more people were using it?

Excellent except for the 2 screaming kids who wouldn’t stop crying and screaming for the entire flight but what are you going to do? The flight was early- good experience

Kept changing the takeoff time and the moved it up so arrived when boarding had already started. Then sat waiting to taxi in for a long time

Leaving at 7 when scheduled to leave at 4:20 - you tell me. Understood there was a ground stop. Then having to "reboot" the plane because of a lighting strike, also understood. But basically the flight was a "clusterf#$%".

With discover in general was very good but from Munich yo Palermo was poor

Wonderful flight! The crew was good, check-in was good and orderly and the flight was uneventful and good.

There was a piece of plastic baked into my buttermilk biscuit! I have a pictures. The flight attendants in first class were really apologetic, and tried to rectify the situation. I I am very appreciative that they were able to give me some packets of pretzels and gummy bears. I understand they don't personally handle the food until warming it up so I know it wasn't their fault. I don't know whether it was a newer aircraft, or different food packaging, but I was happy that when the food was being warmed up - it didn't smell like plastic. Jokes on me with finding plastic in my food.

Horrible experience. They delayed our flight 7 hours!! We had to seat at the airport with kids on 4th July all day!

My flights were all delayed , mostly due to technical issues with AA aircrafts. I had to rebook my trip 4 times . I lost my whole day and finally arrived in LAX around midnight. This was a very bad experience with American airlines , I will always try to avoid flying with them

My flight was delayed close to 10 times over the course of the evening. I was originally scheduled to depart at 7:03 PM but did not leave until 12:33 AM, resulting in over 9 hours spent waiting at the airport. The only explanation provided was that the aircraft kept being swapped, with no clear reasoning as to why. Weather conditions at both DCA and Tampa were clear, so that was not a factor. The only accommodation offered was a $12 food voucher, which was entirely insufficient given the length of the delay. Overall, I was completely unsatisfied with this experience. A delay of this magnitude with no meaningful communication or accommodations is unacceptable, and I would have expected much more from American Airlines in terms of customer care.

if it's a mobile only entertainment experience, please provide a place to hold the device in the back of the seat.

Our flight was delayed to Louisville. What made this worse was they did not have another flight attendant to service the flight. This caused an even longer delay. Then when a flight attendant did show up, she chose to "swap" flights with another flight attendant. Therefore, we had to wait longer for the other flight attendant to come to our flight. This is information that the gate attendant should not have shared. Processes and execution at American are broken. Passengers are feeling it. Fixing this starts at the top of the organization.

Both the gate agent and flight crew did a horrible job of expediting the boarding process. It was simply miss managed. The airplane was late to Tampa. Therefore, they should have expedited the de-boarding process and also boarding process. This did not happen and caused me to miss my connection. I ended up with a 7 hour hour layover just to get home. The overall flying experience on American has simply been degraded. On-time performance is a real problem every single week. This has caused me to consider moving my loyalty to an airline that has better performance metrics.

Flight was on time. Boarding was smooth and orderly. Flight attendants were friendly and professional. Bags came out soon after arrival.

Luggage handling and communication is extremely poor. I landed in india 15th and recived luggage today. Based on my itag the luggage was in Germany. They kept me in dark. Etihad num er in india was non operatuonal. Had to call USA etihad. It should not be so difficullt. I came for 1 week business trip everything was screwed . This is the first and also will be last for me

Due to weather AA chose the poor option of redirecting my next flight to Gol airlines after 23 hours of wait. Their desk is not open during the day. Seats don’t really recline so falling asleep is a horrible challenge. Only one meal for an overnight flight. Poor experience, cheap partnership.

It was ok because it’s a short flight. The attendants weren’t friendly and didn’t serve any beverages even through they announced that they would. Also. The attendants looked messy, not presentable

I have never been assaulted they way I was today in Charlotte - shame on American

Thanks to a delay of an hour of my flight to Philadelphia on American Airlines I missed my connecting flight to Amsterdam. On arrival at Philadelphia he crew on the delayed flight did not ask the passengers to let connecting passengers get off first and I arrived a few minutes after boarding was closed at the original time for the flight to AMS, this despite the fact that I had received a message from American Airlines that departure was delayed by 25 minutes. Overall very poor service, no effort from the part of American Airlines to accommodate the passenger, just rebook the flight for the next day.

Somone switched seats to sit near friend causing us to be disconnected (3) business class. Very disappointed. Staff did nothing.

The whole experience was excellent, O can say out from Miami the best airline to travel with for any European destination. Since the ground staff to the inflight crew attention was great, service on board 10 of 10. Finally the 380 is very confortable and nice to travel.

Boarding was poor. All groups called immediately one after the other resulting in a long queue in the jetty/jet bridge. Seats were very hard and and did not recline on a 4.5 hour flight. No food was available. Plane was cold. There was no entertainment.

I was attacked in the Miami airport and the staff did nothing. On my flight from London to Miami one of the flight attendants screamed at me and demanded I keep my seat in the upright position at all times during the fight so the man behind me was comfortable for the flight. I will never in my life use British airways again

Love the A380 - loads of room. Headphone socket on my seat didn’t work. Sounds like a trivial issue? Well when flying long-haul the in-flight entertainment is what keeps you going so when it doesn’t work it’s a disaster. Pay attention to the details please BA. Spoiled what was otherwise an excellent flight with the usual brilliant crew.

The overall seat and cushion needs to be updated. It was hard and no support. My butt was numb for most of the flight. The food was subpar at best being in premium economy cost. The flight attendants were excellent and attentive during the whole flight. Disappointed I had to select our seats 24 hours prior.

Old tired plane, Uncomfortable business class seat. Breakfast dreadful and meagre. At least flight was on time!

The airline was efficient and accommodating to work with though there was a delay. Appreciate the service and smooth experience!

I don’t understand why a reputable airline like BA would delegate their London flights to AA. Makes no sense to me, as most domestic carriers do such a poor job these days. Terminal 3 at LHR is a total dump
