The baggage handlers broke the handle on my bag that they put under the plane that I checked on the jetway. They traded it out for a less quality bag in Tulsa. But, they said they would try to fix it. Bologna! There was no fixing that bag handle. Someone didn’t care how they treated the bag.

The baggage handlers broke the handle on my bag that they put under the plane that I checked on the jetway. They traded it out for a less quality bag in Tulsa. But, they said they would try to fix it. Bologna! There was no fixing that bag handle. Someone didn’t care how they treated the bag.

Flighty delayed on boarding - then group 1 had to check their carry on bags but groups 3 and beyond could carry bags on - very inconvenient for weekend business trip with no checked baggage. Then delayed on the runway - before take off. No communication from pilot on why or how long. Wifi/Entertainment didn't work for 4+ flight. Upon arrival, attendants announced wrong carousel for baggage claim - everyone was waiting at the wrong place for their checked bags. This was a mess united!

We liked the fully reclinable seats. Had center seats, so it was difficult to talk to spouse. Crew was great

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!

Standard flight experience, but there is only power at the seat to row 20 on the aircraft, on my initial check in it did not say that was the case

Energetic crew - flight full of swiftied going to Taylor's opening show in Paris! Long lines for bathroom made out kind of suck though

I’ve had a couple flights this week on United that were delayed by an hour or more

Great! The plane was decently sized and comfortable. The staff was nice and there was great in flight entertainment

Last minute gate change nearly caused us to miss our flight. Change was not announced or displayed in the main board at the old gate. Terrible communication. When we landed we had to wait 20 minutes because there was another plane at the assigned gate. Not the crew’s fault, but adding 20 minutes to a 45 minute flight sucked.

Nothing beats ANA customer service on my opinion. Maybe because of their Japanese culture (and food). Arigatō

The Airline was not prepared for weather delays. We were held up due to an incoming flight being delayed and so we did not have a flight crew. This caused an extra delay for departure by 2 hours.

When you pay for Premium Economy and you’re promised amenities for the extra money, you expect them to work. They didn’t. USB connector wouldn’t charge continuously. 120v outlet wouldn’t hold anything you plugged into it. The adapter would just fall out. The noise canceling headphones stopped noise cancelling in the first 15 minutes for EVERYONE. No one on the plane knew how to fix it so I couldn’t listen to any movies. I just put in my AirPods and went to sleep. Very unhappy with the crappy Panasonic entertainment system. I won’t buy premium again.

The plane was freezing cold. Normally I’m fine on planes but I needed to toss a sweatshirt on this time.

I missed this flight due to delays on my previous flight.

Crew never smiled, never helped , told me to make my own bed ( in Upper class), never offered a drink

Information when booking said the flight would be with American Airlines but the flight was actualy with British Airways. Check in from Orlando was nice and quick. I agreed to put my cabin case in the checked luggage as it was a full flight. Case came back damaged (unable to put the handle down) so will have to dispose of it. Seats were quite cramped with very little leg room, even for economy. This was the experience of both the outgoing and return flight. Cabin crew were ok and flight time was punctual.

Missed this flight due to the first AA flight delay

Missed connection from Philadelphia to London because flight from DC was seriously delayed. Was re-routed the next day (had to pay for hotel) to Zurich and was given a main cabin middle seat while I had paid for premium. Great job AA!!!

My husband and I pre-ordered our food, but they did not have my husband’s order, and my cheese plate was very average. I asked for a blanket and was told they don’t carry blankets on domestic routs. The flight was on time and smooth!

Original flight delayed several times and finally canceled at 2:30 in the morning. Staff at the gate was not very helpful in resolving problems or communicating why there were delays. I spent 34 hours at the airport before I could leave, they couldn't book me on another early flight even after canceling my original flight. Next flight available after my original flight was canceled was 22 hours later. I will never fly American Airlines again.

The flight got us safely from point a to point b and on time. For a transatlantic flight that isnt nothing. Flight crew was kind and professional. The seats are super uncomfortable (worse than domestic budget airlines) and the cabin was DIRTY.

Long unexplained delay, uncomfortable back row, long waits for trash collection.

Great service on the plane and by ground staff. great prices. I was able to change seats on the plane. The allocated seats cannot be changed when checkin in online. They have to be done at the airport if you check in at the airport or on the plane by asking a stewardess / steward.

I fly to the USA every 6wks on Ave and 99% of the time I fly Aer Lingus. If I fly BA I’m always disappointed. My only criticism is the food. I’m vegan and over the last year it’s got slightly better these last couple of flights but on the whole it’s not good! Salad and fruit salad for breakfast and that’s also the starter and desert for the lunch/dinner and the main is usually rice with fried veg 😳the pasta is pretty good though. That’s been the last 2 meals…. Everything else is fantastic.

The flight was half full and I presume that the next few days are even less busy not sure why they are still charging a premium to change a flight.

Are Longus was fine. I booked thru Kayak and was unable to get my business class seat early. Sat next to galley. Crew forgot to wake me for breakfast.

I loved how they arrange boarding (starting with people seated in back and moving to the front). Flight crew was very polite and welcoming. Seating was ok, I felt like there was enough leg space however it is noticeable when the passenger in front of you sets their seat back.

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

Nice to be on a flight that wasn't fully booked so there were only two of us in the three seat row.

The only problem was there are games on the entertaiment system. The guy behind me played poker the entire time and poking the back of my seat. I hope they remove these.

Yeah you have time and can sit around for a while to be okay for you but if you planned on getting connected flights I recommend not to fly with this Airline it's best they for flying out of the country

Very poor experience the flights were delayed and poor. I think we should have been upgraded on the next flight. I don't think we will be flying again you coming or going in the states and out of the country. This was a nightmare I realize that the flight wasn't so expensive but I still think we should be given at least a third back for the cost of this experience

Iberia was the worst airline we have ever flown. First, Iberia changed the seats I paid $98 extra for. In doing that they moved only my seat 30 rows away from my wife. I had to call to get another pair of seats together and were placed in row 52. Then, when we checked in our seats were changed again to row 29. The food was almost inedible and the videos available on the flight were few and not very good. I paid extra for my seats and have not received a refund. The American Airlines flight was excellent and the food and videos were good.

When our first flight was late, meaning we missed our flight to Madrid that day, American rescheduled us for the next flight the next day, gave vouchers for meals and hotel, and lounge access.

Since our connecting American Airlines flight was delayed we missed our originally scheduled flight. That meant there were no business class seats available, so we got the last two premium economy seats on the next day’s flight.

The main improvement would be better food, although this flight had better food than outgoing flight from JFK to Bilbao.

I forgot to check-in the day in advance that is required for British Airlines so I was very scared that I would not be able to make my flight. However, I was pleasantly surprised to find out that this did not prove to be an issues as the person checking me in at the desk was the sweetest person ever. She helped me get to my flight on time and the crew on the flight were the nicest people I have ever met. Great customer service.

The comfort level was low, but the staff was nice

Amazing, would 100% recommend flying with Iberia when going to Europe

Very bad experience with meal served. I asked for a diabetic meal. Was served everything a diabetic lersn cannot eat. So i ended up not eating the whole flight dinner and breakfast.

We were on flight for 7 hrs and there was no WiFi. Not really easy to use any of our electronics. Def not ideal

Plane had a navigation problem which took 2 hours to try and fix. Didn’t work so then they said they didn’t need it. Could have saved 2 hours

They canceled the flight and would not rebook us within several days

We have a lot to say when BA cancelled our flight the last minute and put us on Air France’s already overbooked flight; and took no responsibility to ensure we are safe and met our travels. It’s day 2 and we have not reached our final destination yet. BA took no responsibility, but were happy to keep the money! If it were not for third party ground staff at Dallas BA we would have not gotten to India. BA has a lot to answer!

Our seats were moved by ticketing agent at Chicago, so we thought we were getting an upgrade. Turns out we were put next to 4 children 2 of which cried or screamed for the entire 7.5 hour flight. It was a terrible experience for us.

The aircraft left 5 hours later than original dipartire time They let all passengers board and sit for 3 hours in a hot air plain with no A/C. Than they made all passengers leave the air plain due to some issues to the engine. Passengers received 1 glass of water the entire time . Than they boarded everyone again and took almost another hour before they took off. I bought these tickets for my 74 years old mother, Julianna Horvathne Kas and my nephew, Balázs Kelemen. Definitely going to request for a compensations!!

Economy class has no legroom so if you have the money worth to upgrade! Food was absolutely horrible! The crew was super nice!!!!!

Very bed boarding, there was overbooked and make a lot of problems and noises

On my way from Chicago to London, I was seated next to a quite heavy passenger. I could barely move. BA should have ensured that overweight customers are placed in comfortable seats and not to penalize also other passengers because BA is not willing to accommodate these passengers and their needs. No respect at all.

First time flying with BA and I will do it again. Staff at airport and on board were very nice and helpful
