Very crowded and the economy seats were the smallest and with the least legroom I have ever experienced. Cabin staff were excellent although the food service was chaotic as they were being each person their food individually instead of from the wagon.
8.0 ExcellentGary, Oct 2026
Very crowded and the economy seats were the smallest and with the least legroom I have ever experienced. Cabin staff were excellent although the food service was chaotic as they were being each person their food individually instead of from the wagon.
The crew were efficient. The pilots seemed professional. It was a bit chilly in our seats. The sheet provided weren’t very helpful.
The Boarding process was great. Particularly since my wife and I require assistance. The flight attendants were amazing. We travel frequently; they honestly were a cut above. 😀
Plenty of leg room, temperature was great and staff was excellent. Would do it more often.
Passengers need to check in big baggage instead of bringing on the plane. That cause inconvenience for everyone. Otherwise flight was good.
Great. Very smooth. Plenty of information. However, wish they would give out a menu in advance of making a dinner choice like other international airlines. The flight attendant says chicken or pasta and there are details about ingredients or spices requiring the passenger to ask which requires the flight attendant to answer many times. So easy to solve this problem. P
All fine save for the abominable catering. Really gone downhill. We found it all inedible.
Late flight caused a missed connection, had to be put on a later international flight without my requested vegan meal.
Half the bathrooms assigned to economy were out of action
The crew members were great. The food was good. Entertainment was average - Could use a wider and better selections of movies and series.
Food was okay. Seats were a bit cramped. In flight entertainment headphone socket didn't work on my seat. Wifi was great, so I was able to stream on my iPad
Selection of movies didn't include recent box office hits. Food was average not great. English sparkling wine is not drinkable. Otherwise, everything was great.
Great staff great experience, made a 2 hour delay very bearable
I was my pleasure to fly virgin on my birthday for my first solo trip ever 🫶🏼
Overall, flight was excellent but check in was very slow for Premium Economy. Economy queue was shorter but we weren't allowed to use it.
Good overall. Cannot fault the airlines. I have had better entertainment systems before ie ice in Emirates but it was not too bad. Food was decent and staff were friendly.
Miami airport needs more thorough signage. It was a long walk from my transport point to the check in desk,
Flight took off an hour late. Had to stay on the tarmac for half an hour after landing. Both annoying.
The crew was very good. However, the equipment was a bit dated. Some of the electronics were not working. To top it, three bags didn’t arrive with me. Two of them were delivered a day later. I’m still waiting for the third bag, I was so looking forward to this virgin Atlantic flight, but, I am disappointed.
My only complaint is that the pocket in front of me was ripped and my things, like iPad and airline magazines, kept slipping to the floor.
Food was very bad Crew was not so welcoming. Chairs was so uncomfortable
This flight has a history of leaving late, however, I was pleasantly surprised that it was not delayed this day. The flight went smooth, except I was in a window seat and the wall and my feet were freezing. I found it difficult to sleep due to being so cold, I also was using 2 provided UAL blankets and could not get my feet warm. This was annoying, but I still made it there on time and safe.
I was very disappointed with my experience at the United Airlines baggage check. The representative was rude and unhelpful. I was required to remove approximately 1.5 pounds from my two checked bags, even though it was a very small amount over the limit. The interaction was unnecessarily unpleasant, and I expected much better customer service. I hope United will review this incident and provide additional customer service training to its staff.
Cree was organized and pleasant. Plane had good seating but as it’s a shuttle toilets hadn’t been thoroughly cleaned (eg. bins too full)
Some flight attendants were great others were cranky. Seats were very tight and sitting on an aisle was very hard as the carts and people walking constantly bumped shoulder and arm.
Although the flight was delayed the crew and the flight itself were very good. Couldn't fault anything and after the disappointment of being abandoned in the US by BA it was a welcome relief to travel with United
Liked fold flat bed. Didn’t like having no window. Didn’t like poor choice of food and being served dinner very late, hours after take off of a 7:40pm flight. Servers not friendly. Food horrible in business class.
The flight was heavily booked so boarding was a lengthy process. The FA’s were rather abrupt during this process but became more gracious as the flight went on. Breakfast (puffed pastry and chewy sausage) was pretty horrible but there was fruit and yogurt which they didn’t mess up. Overall it was fine.
Fight was delayed an hour due to operational issues ,then further delayed due to ground control for a total of about 1.30 hours. Salad was completely frozen and flatware was so cold you could barely handle it. Crew was friendly and professional and the flight was smooth. The aircraft was clean and well-serviced.
Waited for our plane from HNL so we didn't miss connection. AMAZING Service for that, then really clean plane. Nice airline attendants.
The worst seat in any business class. Food are worst then economy class.
We did not fly on American Airlines from Chicago to London. We were rebooked on British Airways (by American Airlines) and our luggage was left behind. A full day delay and lost luggage.
I had to buy another ticket and you haven't reimburse me for it.
Flight delayed 6 hours. Would mean I would miss My connections to Glasgow and my reason for going back. AA staff were completely useless in figuring out how to re ok me. My wife 200 miles away was on kayak offering suggestions. Also NO alerts from AA by phone or text about this delay. Just a $12 voucher for compensation. I ended up on BA
Staff in first class seemed to struggle to provide service to both sections. I didn’t get breakfast though I requested it. I only got coffee after asking the opposite side flight attendant and then could never see them to request a bottle of water.
Seats were the worst i ever experienced — narrow, hard, no leg room and a long flight
In premium economy I was expecting a bit cleaner area. Tables were not very clean. Only one of us received a blanket and pillow. The food was okay. Probably a smidgen better than coach. The crew were very nice but should have done more walk through to at least pick up trash.
After boarding, the AC was shut off on the flight. At business class, I really could not breathe. I was absolutely dripping sweat. I was told by the FA that there was nothing they could do but I could stand by the door until departure. So, that's what I did. I was clearly in the way while the FAs were trying to do their work, but I had to be able to breathe. After that, of course, I had sweated up a lot so was very uncomfortable for the six hour flight.
British Airways canceled our original flight and rebooked us on Air Canada one day later. As a result, we lost one day of our Geneva trip and incurred financial losses for a prepaid hotel night and a day trip that we were unable to use.
Comfort in premium economy is worth it for long hauls especially on the 787-9P Dreamliner with the modern updates. The food was okay. All 4 of us selected the same meal, 2 of us had very dry hard to cut chicken, the other 2 were tender and good. The sides/salad/dessert all very good as far as airline food goes. Crew were very attentive. Will be hard to ever go back to regular economy!
I really enjoyed the flight…and food and the hospitality but didn’t get the food I requested for.
The plane was ancient, and its technology was in disrepair. None of the charging stations worked, and the screens were barely functioning.
It was my experience w Kayak that was negative. I’m never using kayak again
I washed attendant for assistance and she never got back to me. I asked her a second time and she said she would check. She never did. The flight was over an hour late taking off No food service was offered despite over 4 hours on the flight
I chose seating based on me being 6’3 and they changed planes I guess bc I got 2 random Seats that were middle and window and vert cramped and uncomfortable for a long flight….should have been able to get same seating just different aisle maybe especially since we picked them and weren’t random
Liked that our agent at check in changed our seats to allow us to have more space.
Boarding was seamless, crew were great. Less disruptions on the night flight would have improved the experience and turning off lights earlier.
My bags were lost. I waited in a line for 5 hours after I landed and got no resolution to the issue.
Easily one of the best flights I’ve ever taken. Worth it to upgrade slightly. Crew was phenomenal. Just wish the man sat next to me kept his shoes on. There should be a rule about that. But I wish I could take every flight with BA.
The crew could not have been more helpful, my meal was excellent, I slept peacefully until right before landing, and the BA lounge was a godsend. The only negative I encountered was the coffee both on the plane and in the lounge. Not to my taste but that’s a personal preference.
