I was not expecting much as i was not in a premium cabin. I was pleasantly surprised that the seat in economy plus was spacious and food was ample. Party of 5 with 2 parents and 3 kids.

Outstanding in all respects. Early boarding left early arrived early. We were in business class, so was perfectly fine.

The flight and boarding were easy peasy. I was traveling with my 4-year-old, so a smooth boarding experience was especially appreciated. My only piece of feedback is really about where our gate was in O'Hare. They've shoved four gates into a tiny corner of the B terminal and there isn't early enough room or seating for everyone. Not United's problem, but did dent the overall experience.

Dinner was okay but the breakfast was not eatable on the flight San Francisco to Zurich.

I really do not like the basic in basic economy.

There was no screens on board AND the WiFi didn’t work. My seat was broken and couldn’t recline so I couldn’t even sleep. The flight attendants didn’t offer anything to make it more comfortable. It was such an old cramped plane, when the person in front of me reclined I couldn’t even open my tray table. All the United ads talk about guaranteeing everyone gets a screen!

The Wi-Fi was unavailable on this flight for some reason.

On time take off…US cabins look tired and need of refresh!

Marked by flight delays on all segments of the trip. Food in first class cabin was mediocre and overhead cabin storage was not adequate. Overall, the premium charge for first class cabin was poor and over hyped. This will be our last flight with UA.

Fantastic. Smooth boarding with an infant. Never experienced it with any other carriers.

The boarding process and flight were great. However, I waited about 40 minutes for my luggage. It did not come up on the designated belt. Instead, everyone’s bags were on a cart. Not sure what the issue was, but we were not informed until another passenger went looking for her bags and found them.

There were delays on both ends. It made it less than excellent. This plane was great though

AA1537 the AC was not working properly. It was very hot and uncomfortable.

Worst experience flying American Airlines. I fly with them often, so I was super disappointed in the service I received at gate 30 in LGA on May 24, mid-day. The flight was delayed twice. I was patiently waiting in the American Airlines lounge when I received the notice on my app that the plane was boarding 45 minutes before its newly re-scheduled take off of 4 pm (from the orginal 1:45 pm then 3:00 pm). It took me 5 min to travel from the lounge to the gate and when I arrived there at 3:20 flight gate attendant told me the flight had closed and that they announced for passengers multiple times. I showed them the notification on my app and they were really rude and unempathetic. The person who rescheduled my flight at customer service wasn't any happier but was at least helpful in getting me on the next flight.

Flight was 1/2 hour delayed leaving Phoenix. Otherwise it was an average flight. Flight crew on this trip was very nice.

Everything was great except for the wifi was junk. Crew was super friendly and helpful

Was lucky to have a employee at the AA checkin counter that had compassion and understood they ordeal that we went through with our original flight being diverted, needing to stay in the aircraft and then flying to the original destination; adding hours to the trip and forcing us to miss our connection and our rebooked connection. She was able to get up on standby on the highest priority on the next flight to the closest airport we need to be at and it all worked out despite being many hours late.

We were redirected to a near by city due to weather and had to stay in the aircraft before flying to the original destination's airport. The whole delay added 3+ hours and were were not offered any snacks or water.

I wish that we wouldn't have to go through TSA again on connecting flights.

Priority baggage, golf bag lost causing me to miss function the next day. Baggage in general in Charlotte has been a mess lately.

Plane could have been cleaner. There were many crumbs and crud around the seat mounts.

Short flight so not much to rate. Surprised I had to pay for a soda.

the room on the plane was good but that is because flight not sold the other three seat and I had room. the food in terrible.

First the price I paid was excellent, my flight was full, but my seat was roomy. The one downside to the experience was they had games on the entertainment console. The guy behind me poked at my head about half the flight. I hope they get rid of this feature.

Very good need to offer better choice of food for business

They should. Heck planes more often not when they are suppose to be leaving causing delays

Crew was fantastic got lovely food and plenty of water. Entertainment was good. Never had to ask for anything. Left on time and got to Seattle early. Luggage did not take long either.

Always find Aer Lingus reliable and good value for money. Food on this flight was pretty basic and the headphone Jack at my seat only worked for one ear. Little disappointed in movie selection, limited on recent releases. Staff are okay - but I always buy a cheap ticket so not like I expect first class opulence anyway!!!

Boarding was so quick, flight was ahead of time which is great and the pilot spoke clearly and was letting people know everything, amazing, love travelling with you 😊

Great hospitality and service! Seats are better cushioned then some

Will try to not fly with them again. Delays because of weather but got redirected to an airport where I could not make connection.

Staff didn’t care in business class. Closed the door on my mom while she was on the jetbridge and flight attendant told me she would make it from the connecting flight. They lied. My luggage was damaged on arrival. No success in filing damage claim.

Crew was super rude in business class. Not friendly or helpful. Luggage was damaged and was told to file with United and that was unsuccessful.

The connection at Frankfurt was chaotic and nearly missed the flight to Atlanta. They made was wait for busses to transfer and it took ages

There was a screaming child just behind our seats. This prevented us from getting any sleep during the night!!

my flight was at 3:45 after that they delayed to 4:40 I have transit from Chicago to Frankfurt and Frankfurt to vina airport from vina to Erbil buy the Time I come to Frankfort my other flight left me I have to stay at airport all day with my 5 kids ask for help no one help me I spent at airport almost $450 just for food was horrible flight ever I call and ask for hotel from united customer service they been telling me we can’t provide any hotel I need some refund or fixed my flight when I return to America need some one respond my email

My experience would have been greatly improved by arriving on time to connect to my Porto flight. The staff that dealt with the aftermath of the late arrival evidently booked my group into a hotel in Frankfurt. This reduced my time in Porto Portugal a day and half. I do want to commend Jorge Klein for his hard work. He spent a great deal.of time trying to rebook the flight and he eventually did rebook for the next day and did provide accommodations for me overnight. This was a big issue for me and the group I traveled. The rest of the trip was good.

Not your fault…..didn’t get my drink until just before landing….bumpy flight.

Boarding was a zoo. London ground crew was useless. Poor communication regarding where to line up. We were group 2, and everyone was jammed in together. Ground crew didn’t seem to care.

We liked the direct flight from Frankfurt to Orlando, however, it was a little confusing as I thought I was traveling with Lufthansa from Izmir- Frankfurt-Orlando. We were not able to check in online twenty-four hours before the flight from Izmir. One lady in our group wanted to check two suitcases in Izmir, but was not allowed to do so. She was allowed to take the extra bag into the cablin. Others in our group were able to check two bags. In Frankfurt several in our group were given stand-by boarding tickets, which worried them. Everyone eventually was allowed to board, but it caused them to worry. I didn't have any of those problem.

My worst flying experience so far. This flight was delayed a total of 42 hours and diverted to New York before it was finally cancelled. It was delayed 4 and a half hours in London. As we were scanning our boarding passes at the gate they advised that the flight was being diverted to JFK since the delays caused us to missed the open hours for Charlotte international customs and immigration. We were assured multiple times by airport personnel, flight attendants, and the Pilot that we would land at JFK go through customs and immigration and then reboard the plane to fly to Charlotte in the same night. When we landed in New York the pilot advised us as we were retrieving our carry on luggage that we were delayed till 10am the next morning and to see guest services to get a room for the night. During this time I had to purchase a room for a family member in Charlotte which drove over 4 and a half hours to pick us up from Charlotte. This could have been avoided if American Airlines had been up front about the delay. Then after standing in line for over 2 and a half hours at guest services we were taken by taxi to a hotel 30 minutes out of the way. Luckily I looked for other flights that night and found one at 8 am to get on. The initial flight which we were scheduled to fly to charlotte in was delayed 12 more times and was finally cancelled 42 hours after it was supposed to land. I am unaware of what happened to the guest that were supposed to fly on the flight after we were placed on another flight but 42 hours in delays for a direct flight is absolutely ridiculous.

The boarding to Gatwick was a breeze but the boarding from Gatwick was a nightmare. The onboard service to Gatwick had a lot to be desired but the onboard sevice from Gatwick was amazing ! Very nice,friendly and funny ! Would I recommend BA to anyone.? ! Yes I would!

Is it American Airlines or British Airways? This is so confusing. I got it from Portugal.

Appreciate free wine and entertainment plus good meals. Also leg room

Really quick check in and security at Heathrow Terminal 5. Staff on board were lovely and very friendly. Could have provided a few more drinks on the flight but they were available at the back of the plane.

they are improving. The crew from Charlotte to Tampa was outstanding. SMILING and trying to be helpful with the customers.

It was a flight operated by Aer Linus for BA and the plane and crew were very good but the food selection was average.

I like the food this time compared to my departure. I’m seated at the isle so it’s comfortable but I have to pay $124 for seat selection

Flight delayed an hour due to plane maintenance issues after getting in line to board. Issue was plane galley ovens which eliminated hot meals for overseas flight. Cold selections were limited due to availability. Drink and meal service (already an hour delayed) was very slow. Upon arrival in Nashville, had to sit at gate for about 15 minutes before disembarking with no explanation. Local police then boarded plane as we were disembarking so maybe that was the issue.

Leg space was not enough. The meal was not satisfactory.
