Seat back monitors and outlets were dead and not working.

Seat back monitors and outlets were dead and not working.

Everything was great except for the seat. The backrest would not stay in the upright position.

I usually have a positive experience with Delta. Complimentary upgrades are always nice!

Flight delayed about 2 hrs so it made it a VERY late night

The crew, food, and entertainment were all good. But my screen had some sort of bug where if I turned it off, it would turn back on after 2-5 minutes. At full brightness. It made it very hard to get any shut-eye on the overnight flight. Also, the older Boeing plane, while nicely cared for (and no doors fell off 😅👏) doesn't have the nice air quality of newer planes. So I felt a bit greasy by the time we landed in Sweden.

It was a crowded flight. They did the best they could.

Service was good for such a short flight. Small plane but smooth flight.

Worst flight in my life. Only was scheduled for a 45 min flight to get our connection flight. It was late by 40 minutes and we missed our connection. Delta was totally useless trying to help and unable to get my family on the next flight because they overbooked it Thus had to get a hotel at my expense and lost a day at Disney as a result. Cost me about a $1000 if you add 2 hotels meals shuttles etc to get thru the day Awful customer service by Delta in Detroit totally useless people

The experience was good and the flight departed on time and landed early

The flight was delayed but we got to our final destination.

On time every leg of the journey and exceptional staff at counter, gate, and on board. I haven’t travelled in US for a long time and was genuinely surprised how pleasant this was.

The delays (5 hrs) were a comedy of errors, and the multiple safety issues encountered were very concerning.

Trip was smooth bumpy from the wind but no issues at all the crew attendant was very pleasant and had great customer service

I liked everything about the flight. The service was excellent!

The customer service was excellent! Check-in, baggage check-in, boarding, the flight went very smooth.

Delayed a day due to snow storm. Was upgraded. That kind of made up for significant delays from FLL to COS with no compensation or acknowledgement.

The Polaris experience is top notch. From departure lounge to arrival lounge. Everything was top notch. One of the best first class experience

The leg space between me and the seat in front of me was excellent.

Over two hours wait to get wheelchair assistance from arrival to the departure gate for LA was unreasonable even though there appreared to be heavy demand.

Crew is way too many times on the intercom re explaining the same thing

Flight was fine. It took an unusually long time to have baggage delivered to the carousel in ORD.

I arrived to the airport 2 hours before my American Airlines flight was scheduled to take off. I have TSA pre-check. The airport was crazy packed when I arrived. After momentarily standing in the pre-check line, the TSA agent said that I am not pre-check. Of course I said that I am because I entered my KTN number on all my traveling sites and programs. I had to get out of line and go back to the AA counter to discover that American Airlines did not add my KTN to my boarding pass. I had to call TSA to find out my number, then have AA enter it onto my boarding pass. The emblem would not load onto my boarding pass. By this time, I decided to use my Clear in order to get through TSA but the line was ridiculous long. By the time I made through TSA, I missed my 11:08am flight and was re-booked for the 5:30pm. This is after the AA employee told me I should have gotten to the airport early. AA use to be a dependable airline not I use them only if I have too.

Flight from SBP to DFW 1. They rerouted us through PHX 2. Delayed flight out of SBP for 3 hrs so we missed our connection Downgrade on rerouted flight. Back of the plane, center seats, didn't sit together 4. Return flight out of DFW same exact thing. Delayed, missed connection, Downgrade + they lost our luggage! A complete mess.

Do not eat the bagel! Otherwise, good albeit late, breakfast in first. Boarding downgrade only because flight was delayed due to plane change due to undisclosed problem with original aircraft. I did not use entertainment.

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

Fight crew was not very attentive and the bastions were gross!

I don’t think the flight attendants are happy. They do not seem to be friendly or welcoming.

Gossipy flight attendants talked the whole flight about bar hopping and dating.

Didn't like the 6 hour delay as it caused me to miss all of my connections. Still, I did get home safely 14 hours late but exhausted.

Flight delayed, boarding time kept changing, not good. Nee firm information given each time.

I like the team but I don't like the food you provided with money. I want free food and free water.

My wife and I paid for seat selection to be together. My wife and I were on separate rows and the excuse they gave was they changed the plane. Also, I have celiac and asked for a gluten free meal in the ticket profile which they did not have.

I’m hoping for WiFi included. Everything else was very good

All corners have been cut and it’s a cheap experience that no longer is distinguished from most other cheap airlines

This flight was a code share for both Iberia and American Airlines and run by what I assume is a charter company Level. It was difficult if not impossible to get a seat assigned, check bags or use any customer service functions. I would skip it!

Rude security cunts. However the lady that issued my boarding ticket when I was flying back from New York was lovely & helpful!!

Appalling! The flight was delayed by 3.5 hours and the American Airlines staff at the airport where nit very helpful. Once boarded, the flight crew were unhelpful, the food was poor and the aircraft was tatty.

I called prior to flying to confirm our baggage allowance which was 5 bags. On our outbound flight thee were no problems. On the return flight we were charged for each bag totaling $400! We are working with customer service to resolve the issue.

it would good to have at least something to drink...

Everything was great, except the food, which could have been flavorful.

My baggage did not arrived with me. Took 3 days to get it after so may calls and follow up

Terrible! I missed my flight to my final destination and British airlines and American Airlines keep pointing fingers on each other’s. Nobody wants to take responsibility

Terrible. Flight was 3 hours delayed and I missed my other flight to my final destination

Overall, terrific service, accommodations, and experience. Only reason comfort was rated lower was because it was difficult to keep a comfortable sleeping position for the overnight flight, but I also had an economy seat.

Not sure if the crew were experiencing something unknown to me,but the service of passing water was non-existent.In addition,please take consideration when providing yogurt as alternative for breakfast as some of us, could be lactose intolerant.. thanks

Very cramped seats in economy, difficult to get comfortable with your legs and feet and back. The seat width is ok but I’m average size. Food is HORRIBLE. Crew is friendly. Delays and very tight connections made it tough for navigating. We would have missed our connecting flight if it wasn’t delayed too. The terminal transit was slow and normally every 10 minutes before 8pm, after 8 pm is every 30 minutes!!!!! No free wine or drinks!! Below average attitude.

Leg room was better than expected. Lavatory’s were easy to access.crew was grea!

Horrible seat allocation. Boarding was slow. Food was average and so was entertainment. The TV terminal didn't work and so had to use remote.

Lost one checked bag.and wasted 30min waiting and filing missing baggage report. Very unsatisfied.

I’m not happy because I discovered there is something wrong and my miles have not been getting put on my AA account. So this needs to be fixed because I have traveled a lot since October and none of my miles are registered
