It was the hottest flight I’ve been on in a long time. The female flight attendants were not nice.

It was the hottest flight I’ve been on in a long time. The female flight attendants were not nice.

Very disappointed in the crew as they did not pick up my trash nor offer headsets

First The flight got delayed because one of the crew members was late and we couldn’t board until she arrived. Then we all boarded and got held in the tarmac for another 30 min.

My service light was on 15 minutes before I had to get up and find a glass of ice. And I was in business class. The meals were not for either my wife and I. She did not eat the entire 10 hour flight and I managed a bowl of soup. I was expecting much more from business with what we paid.

The only thing I would say is we tried to get on a standby earlier flight, but with our fair we couldn’t. That seems senseless to leave with open seats..

It was delayed but other than that it was great.

Crew was good. The reservation got mixed up and they didn't have my TSA number. I am also a Silver Medallion and wasn't able to use Sky Priority.

There was supposed to be a meal served, but there wasn’t and the major toilet was out of order

At first, we were on the runway for about an hour, literally. The Captain did explain that the Control Tower just had a change shift (sounds like an unrealistic excuse) and then that we had to change a runway. A regular economy seat is made for 12 yo twiggy. I understand Delta wants to push for an upgrade, but after sitting in a Comfort seat and in First class. I would say First class is not worthy of my money. The landing was delayed because of the weather in NYC, I don't hold that against Delta, of course. The Captain did alert us to that upon takeoff in Vegas and again as we reached NY.

The food was good. I ate gnocchi with marinara sauce and cheese, salted caramel tiramisu. And later in the trip cheese calzone. I watched 3 movies. The selection is really good. Have new and old movies. The flight attendances were nice and cordially. Overall the 6 hours trip was really pleasant ☺️. Planning the next trip.

The staff on the flight were utterly brilliant; there was a young man who was particularly exceptional. Boarding was quick and seamless, and service was great! Seats were fab, as was the entertainment and its ease of access

i’m The staff on my flight were amazing as always, beautiful professional staff, they do amazing job. the food ? room for improvement

The agents at the boarding desk were not very helpful, however the hostesses on board the flight were great, the food was ok, and there were lots for choices for entertainment. I was stuck in an middle row seat which was a pain on a full flight, but otherwise the flight was great.

The man in front of me reclined the entire flight, including during meals, which was aggravating. My screen had issues with brightness and kept flickering in and out.

Still some confusion about my baggage which was disconcerting. It was nice that there was extra space on the flight for comfort reasons. Staff very friendly

Everything was smooth and the meal was delicious. I really appreciated that Aer Lingus still offers complimentary beverages, food, luggage and headphones. It was nice that the main meal also featured some items typical to Ireland including the wheaten bread and Kerrygold butter. I generally found the flight a quite relaxing and enjoyable experience.

The seats are so close that you have 0 room to move. Not acceptable for an 11 hour flight.

Easy process you definitely need 3 hours to get on board from Fuminchino airport

Amazing, not too crowded, great temp and the meal was good

Seats are small, but comfortable and more space around you, so for a normal person the seats are perfect. If you are a big and fat individual, I would not think the seats are comfortable. All else was good and normal. Lots of movies to watch.

Plane was in good shape, multiple passes from the drink cart, and one of the smoothest flights I've had in a while.

The flight was delayed by about an hour due to a maintenance issue which later then required a change of planes. The crew was great and friendly. The in-flight entertainment did not play properly on Apple Vision Pro in a Safari browser. Although the movie trailers would play fine, the actual movies themselves just had a black screen with audio. There must be something with copy protection or something that isn’t compatible with the Safari browser on Apple Vision Pro. The free inflight Wi-Fi for American Airlines Advantage members is a nice bonus. and is great that they aren’t charging extra for things that have become basic utilities in 2026, like internet access.

Mostly great. Only issue was with the WiFi. Halfway through the flight it was spotty and I was unable to work as I planned. This impacted my work products as I am traveling for business and it was an unexpected hindrance which was inconvenient. Flight here was amazing. For a 5 hour flight something more than a Biscoff would be nice but I’m just swinging at windmills I guess…

Better service. No food options, but we did get drinks and a cookie.

We were 4+ hours delayed. AA is absolutely obnoxious. They just kept pushing back the time to the point where we did not get into Vegas until after midnight when we were supposed to arrive like 845pm.

We will be writing a long, detailed letter to corporate about our awful experience with American airlines.

Very helpful ground crew after an earlier flight delay and being rebooked on a different flight.

I was a little disappointed of not having an android charger. Only one it was for an iPhone. I've flown American in the past and had access to one.

Almost everything was outstanding. First, we boarded on time and the flight crew did a great job getting everyone seated. Then the pilots took their time and care to make sure the plane was full de-iced three times as there was a bad ice storm a few hours earlier. The plane ride was smooth and comfortable and even the economy seats had decent room and comfort. Flight Attendant Lisa went above and beyond to make sure I was comfortable - she is outstanding. The only thing wrong with the flight, and it is something which needs to be addressed, is that the gate to gate time was over 6.5 hours and not one meal was served. The only thing offered to eat were two small cookies for a transcontinental flight - unacceptable. Charge me more but give me a meal for a long flight. Thankfully Lisa found something for me.

I got bumped due to weight restrictions even tho there were empty seats on my flight. I got put on an other flight with a stopover. My flight that originally was going to take 5-6 hours ever up being 14+ hours and my luggage arrived to my destination without me because I was made to check in my luggage on my original flight when I was deemed ok to board only to be asked to deplane. Worst flight experience.

America Airlines was great- The ticketing from Kayak was poor and unnecessarily complicated

Over 3 hours and 25 mins delay, entertainment screen froze on me for more than half the flight

they couldn’t not serve coffee or tea as the water that was boarded was not potable. the veggie food was lousy. tasted very sweet. there was a crying kid a few rows ahead. what about the difficulty caused to other passengers because the kid was crying so much. parents should know their kids better and not travel. it was a very difficult situation. would not recommend this airline next time.

the internet connection was poor. and the change of time

Horrible, they detoured my first flight to Roswell and the communication on why was very poor, We arrive late then waited 20 minutes for them to set up the bridge. I arrived at my connecting flight gate and was told my seat had been given to someone else even though the flight was delayed. We then get to customer service and the computer went down for several hours. The person at the counter was eating their lunch while trying to help me get a flight. Dhe then rebooked on a flight with a connection that was leaving two hours prior to me landing. So I had to then stand in another line to get rebooked. I missed my trip to Morroco and waited 7 days to finally get my luggage. It was a nightmare.

Based upon our entire experience with Iberia, we will never fly the airline nor recommend the airline to anyone. The flight to LA was fine and the crew on this one flight was god, but Iberia treats its customers (us) horribly. There was not one flight on this trip that they did not treat us poorly. We were bumped, lost seats, lost luggage etc all on flights we booked over a year in advance. Not one leg with Iberia went smoothly. And now they have lost our luggage somewhere in Madrid. This is a horrible airline. A truly horrible airline. And Underpricer recommended by Kayak is horrible as well. The lesson learned is to book directly with an airline and stay away from Iberia at all costs.

Very cheap airline, not worth the price. And they almost lost my luggage at JFK during a direct flight. I can't believe I paid that much money for a horrible 'premium economy' flight. Just fly economy on the cheapest end; premium economy is no different. Very very poor.

Charging $300 to be able to pick a seat next to your wife was nothing less than extortion.

I paid for premium economy but BA oversold the seats and we ended up being downgraded. Not acceptable given how much we paid for the flight. We were also separated to 2 different areas so not only did we not get the service we paid for, we didn’t even get to sit together. I’m not happy at this treatment by BA because of corporate greed.

How to get an aisle seat without paying extra? The young lady next to me was assigned the seat.

My experience on this flight was good. The seat I had had a lot of leg room, but it was so close to the aisle that the flight attendants kept bumping into my visual monitor connected to my seat to watch tv.

It was fine, but it cost me twice as much to return to Boston as it took me to get to Heathrow from Boston two weeks prior. I flew on Jet Blue over and it was half the cost of British Air.

Staff and comfort were great but first choice meal was unavailable even in row 21.

I have flown on British Airways, many many times and will continue to do so! Always the greatest service and staff!

canceled flight. needed to fight to get same fare class. now they have canceled return.

Online check-in not available from Istanbul to Las Vegas. The check-in process at the airport was extremely and inefficient period. Took us over an hour to check in. Besides that, everything else about British Airways was good

Seats not as comfortable as I had hoped. Food was very nice, service was fine. Entertainment options very nice. Had thought the premium economy was a more plus 2-3-2 layout but it was a 2-4-2 with seats not as wide as I had expected.

My bags never made it on the flight and I now have to wait for them to arrive hopefully tomorrow. You can’t even track your bags in the app to see where they are since they didn’t arrive. You have to file a claim and then wait for them to inform you when you will receive your bag. We were already delayed for an hour due to baggage so I don’t understand how my bag didn’t make the flight.

My luggage did not make it. Will avoid Heathrow and British air

Overall flight experience was good. Unfortunately our process getting to our flight was a hit or miss. Our flight was delayed perhaps for the best as getting from terminal to terminal is very long and security had problems with the machines that delayed us getting to our flight. Heathrow security could care-less that you have a flight you are about to miss!
