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

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

No meal service to the back of the plane as it started late or was too slow to get it out before it was time to land.

Terrible, if possible won't be flying again anytime soon!

Efficient boarding and early departure. Very smooth flight. Early arrival in ATL. Great flight.

We purchase first class seats for the first time for multiples of standard economy ticket. There was no access to the club lounge and no priority boarding. The meal and the service once on the plane were superior and the seat was nicer, but not worth the price difference. I will be happy to seat in economy and spend the difference on more travel.

The business class seat is exceptional. I wish the food is more palatable.

Wonderful in-seat entertainment with seatback screens and huge selection of quality movies. The ability to bluetooth connect headphones was amazing.

the entire flight felt off. The crew seemed uninterested and disengaged. The food service was really bad - overcooked, bland, weird food service. They actually woke us up to serve chicken wraps in the middle of the night, after dinner and before breakfast. Made no sense. Ultimately, I was glad they did though, because the breakfast had been held for so long it was inedible. Eggs, potatoes, sausage - all disgusting. We were asked to "honor" the lavatories for premium customers and stay in our own cabin: this was also strange. So people in economy didn't pay enough to use the closest toilet to them??? It's a toilet. All in all, not the experience I have come to expect from United Airlines. The return flight from Paris to SFO was better, btw.

Smooth and easy boarding, comfortable for the entire 5 hour flight, and the seat back entertainment was great! I appreciated all the features, from location info and maps, movies, the ability to connect with Bluetooth headphones, and good selection of movies. Food was good, normal airline snacks (I didn’t purchase anything)

Overall, the flight was good. Lounge access should be with all business class tickets.

Ceiling fell down and had to have maintenance come and duct tape it up. No WiFi on the flight.

I appreciate that I finally got the seat I paid extra for this time. Thank you

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.

Plane from partner PSA was filthy. Plastic needs to be thoroughly cleaned. Really disgusting to look at and wonder about cleanliness of parts less visible.

Arrived early picked up my bag in a few minutes- great trip - thank you

I like that the flight attendant was very attentive and helpful. The meal menu could have more of an variety of food choices.

We missed our flight and got stranded in Miami where we had to rent a hotel we could not afford. they would not work with us because they said it was weather related even though the gate attendant said it was not. I could go on but trying to get satisfaction has wore me down, which I believe is the intent. My only solution is to never fly AA again.

Overall it was a good flight. Because we traveled on a Saturday we were upgraded to FC since my wife and I are both Executive Platinum. The only areas for improvement we noted are better snack assortment and perhaps a little nicer plane as American is flying some older planes now. Everything else on this flight was excellent, which is frankly not the norm for American since we have had multiple issues on prior AA flights.

Didn't get a seat assignment until the last minute even though i picked a seat.

Flight was smooth, quick and felt safe. The 2 delays not happening would have been better but I guess that happens in the airline industry

The gate agent made me check my carry-on in Denver, even though I've traveled all over taking this case on the plane. Beware folks. Food in Premium Economy was quite good - excellent blanket! Flight attendants on the Heathrow-to-Budapest flight on 3-27-2026 were quite snappy. I got a frown when asked to unscrew the water bottle cap for me (I had a cast on my right arm). Also woke up right when they were handing out biscuits. She had given my rowmates one and was in the process of giving water when I asked for a biscuit. She scolded me and said, "You snooze, you lose". She did give me one, but I thought that comment was uncalled for.

Wish the food and overall service was better. They treat Business class passengers same as economy

WiFi wasn’t available to economy until the end of the flight.

Very good staff members with sincere passion and responsibility in their job.

We paid for Business Class seats, but system did not have us and they were not available.

Very please with the seating that the Kayak staff booked for us!

Worth every penny to upgrade to BC. Treated and felt more like First Class

I paid for a very expensive Business Class seat to and from Cairo Egypt from Charleston SC. There was partnership from states to London using American Airlines. That leg was amazing. The British Airlines leg was a joke. They used the standard no leg room 3 by 3 seats. A tray was put on the middle seat. The trip was 5 hours, from London to Cairo, thus my BC purchase. There was no screen proving tv/movie options, only a small device plug. The fold down tray and the bag of peanuts were typical of normal short run flying. The one toilet was located in the galley. We all got to know each other well. This was my first and last trip with British Airlines. I now understand why they would NEVER give me a seat chart so that I could make a selection.prior to departure. It honestly would not have made a difference, there were less than 50% of occupied seats. Apparently everyone got the memo but me. I have never felt so cheated as with that trip, got to so another going back to London, yeah. I will be sending a letter to customer service and asking for a refund. I will be photos comparing the two BC legs. OH, one more thing. The FC ticket holders got bulkhead and exit row seats. I know they had to be thrilled

Good service, food and comfort in World Traveller Plus. Entertainment was poor - no wifi on the way out and barely working on the way back. Not a great choice of entertainment on the seat back tv.

Late! Late and late! More than 1hr 30mn. This sucks when it is the last of a 4 flight journey. I missed my dinner! Which is not nice on Valentine’s Day!!! But better than the gate next to us, the poor Chinese people were rebooked to the next day flight. AA had to call security as it became very heated with the passengers! It was a mess at DFW that afternoon/evening. I wish they had some food for the people who travel as part of international journey. Indigo does it in India and it is fantastic.
