Lounge was top notch h with great variety of food and drinks. Cabin crew were great. Smooth flight.

My seat 3G did not go down fully and the buttons were not working properly

Food was the worst I’ve had on a VA flight. Normally it’s a lot better

The staff was not very polite but the flight was very very nice and comfortable and the entertainment was great

Security area in terminal 3 needs to be made much nicer. Less claustrophobic and use of glass and big ceilings wouldhelp

accomodating check in staff, friendly flight crew ( a crew member was speaking tactlessly and was overfamiliar with passengers

Seats need to be updated. Allowance needs to be made for dinner service at an alternative time

If I could fly Virgin Atlantic airlines to every place, I need to go, I would. Leaving Heathrow through the special virgin air entrance, security is completely white glove service. I love this airline. From ticketing agents to flight staff everyone tries to make it a wonderful & happy flight experience. I wish other airlines copied the positive culture of Virgin Airlines.

Premium was very comfortable. Food was delicious. I had specific diet requirement and Virgin Atlantic ensured it was provided. Onboard crew was very friendly and caring. Extremely smooth journey. I wonder how upper class experience would be. Perhaps one day, I will try upper class.

On arrival to JFK it to 3.5hrs to clear immigration, as only 3 booths open. Almost missed connection

Very friendly and helpful staff on board and United was excellent when I missed my onward flight due to the delay in London. Very well organised meant much less stress

First time flying with UA and it was a great experience. Thank you

Short flight, but no drink/snack service. The flights both going and coming were delayed.

Staff on board was excellent. Positive upbeat helpful- like it used to be.

United has come a long way, it’s been a fantastic experience traveling with them.

The flight attendants were very rude, beyond comprehension. I took a business class from London to SFO for the first time on United. When I asked for a second piece of bread during dinner, the serving attendant threw a 3rd bread on my plate and said, “here. You can have this one too”! I couldn’t believe the rudeness of the attendant. Most all attendants were very rude, unhelpful, sing the food was absolutely disgusting. Never fly United internationally in business class. My flight back to SFO was a nightmare!!

Our experience on United Airlines was extremely poor. The plane was extremely cold throughout our entire flight- which multiple people complained about- and we had to wait 2 hours to get a blanket which was too thin and barely helped warm us up. As well as this, none of the entertainment features were working so we had to sit through a roughly 10 hour flight with nothing to keep our attention, including the actual flight path screen. It was an extremely disappointing experience and I would hope that this gets fixed if we ever choose United Airlines again.

Cabin crew was very friendly, requests were satisfied promptly and cheerfully, and the cabin was reasonably clean when I boarded. The United lounges at Newark and Heathrow are always well-run and comfortable, especially Newark. I look forward to the new lounge that will be part of the rebuild of Terminal 2 at Heathrow.

The senior flight attendants were amazing. Totally different vibe from other carriers. Easy 10 hour flight in Business Class. Great food. Good humor as well.

I was lucky to sit in a seat with legroom in economy . The airplane felt like it was 100 years old, seats were very basic, barely reclined. Food was alright , staff was ok but not the friendliest. But all in all ok trip, perfectly on time

Plane features were VERY old and outdated. footrest cushion was completely lose, plane felt dirty and a bit grimy. i was in business class. the lead flight attendant, Mary made a few announcements that didn't seem to put the cabin at ease (it didn't necessarily bother me, but could have bothered others). she said "the seat cushions aren't FDA approved, so you have to put them on after we take flight." everyone had already applied the seat cushions, and saying something isn't approved for flight may cause alarm. she also said at one point over the announcement ... "we can't get up because we are too afraid of the jet stream impacts" -- again, not helpful to those who are nervous fliers.

Extremely comfortable airplane, everything looked brand new, how lovely! My seat in Premium Economy was ever so comfortable, I did not suffer the usual backache I suffer when doing the transatlantic flight. It felt like seating in a reclining armchair. I loved the foot rest, did not need to use the portable device I usually carry along with me to replace one. I loved the spaciousness in front of me, and that there were only two seats (Instead of 3 in coach) in the window row, wow what a difference in comfort. Coach seats are always just a little narrow for my hips. The support of the cushions was great, firm and offered good support . It was easy to come out of my aisle seat, although I'm 70. The staff was courteous, both meals were delicious, very carefully prepared, and creative (fruit + cheese for the second meal, instead of the usual bread sandwich)

The plane was up-to-date, and the free wi-fi was very much appreciated! All of the ports functioned well, and the entertainment choices made the flight much more enjoyable. One of the flight attendants was unfriendly, but the flight was enjoyable overall.

3 hour delay before takeoff & another 30 minutes on the plane before taxi to runway

The gate got changed several times and the flight was delayed over an hour. Awful experience

It was an older plane. First Class was not especially roomy or comfortable. It was a short flight so there were no meal but they did offer mixed nuts which used to be normal but now is rare. Crew member was very polite and professional.

No Snacks or Entertainment. The flight was short, snacks should still be given.

Everything was fine. Flight boarded and departed on time. Seating was spacious enough for my carryon to fit under the seat in front of me. No complaints at all. Flight even arrived early.

Boston ticket agent Cheryl Porter is WONDERFUL. Our Iberia flight to Barcelona was cancelled the morning we were scheduled to leave and Cheryl was our super hero - she found us seats on a flight to London and on to Barcelona. Truly a “can-do” attitude which we appreciated so much after the Iberia ticket agents told us there was “absolutely nothing they could do”. (As did the customer service agents at Iberia’s call center) Ms Porter is truly a wonderful person who genuinely cares about travelers!

Nothing wrong on this flight but nothing special. It was oversold and they had to bump people which is always bad.

Flight map did not work. Crew was great, food was good, plane took off on time and landed early. That's all I can ask.

Paid for exit row at the back of the plane. Window seat with lots of leg space. Food was inedible (as usual). Brought my own.

Not what I expected for the last leg of a $5100 business class experience. Boarding was a nightmare. The flight was delayed and I had to keep checking my email to ensure I was at the right gate since the airline or the terminal had no clue until 15 mins prior to boarding. Food was gross, limited drink options.

Flights scheduled with impossible connections - Lufthansa apparently believes it takes 7mins to change terminals, go through passport control, re-clear security and walk 1.8kms…..and everything will work perfectly (which it never does at Frankfurt). No staff on hand to assist with transfers on delayed flights. No transfer guidance provided by app. No compensation offered for 6hr delay to connecting flight.

Crew were friendly and very helpful Plane was clean and the legroom is standard. Overall a good flight, no complaints.

Other than problems with checking in and uploading passport info everything was great. It would be nice to be able to manually input passport info. Often while traveling the bandwidth has problems uploading pictures

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.

Horrible flight attendant in back of economy that screamed at me, have already reported to United. Horrible food - for Gluten free, why would you assume the person is vegetarian? I was served some kind of horrible curry bean paste and multiple cold rolls and soggy vegetables with no seasoning... um no!

Knowing that there was weather in other areas of the world, united airlines should have planned better than it did. The flight was 5 hours late. United has no regard for its customers

Flight itself fine, big problem with KAYAK. Revised e-ticket sent in July stated departure LHR 10:55, arrival SFO 13:45. (a believable local arrival time given flight length and time difference). When we got to LHR there was no 10:55 flight to SFO and were advised that in fact flight LH2473 was arriving in MUNICH at 13:45pm, and that we would need to get a connecting flight arriving in SFO at 18:55 local time - over 5 hours later than expected. 1) you the booking agent made an error on the revised e-ticket you sent, omitting the Munich stopover and incorrect SFO arrival time. 2) I booked a DIRECT flight and 3) we had to cancel plans this end as a result, even though the team at LHR did a great job moving us to a later direct flight getting us in 2 hours earlier than the flight from munich would have.

Not good because in this cancelled and then rebooked flight BA put me and my husband in both middle seats when we were originally seated together in original flight and i was in aisle. I hate sitting in the middle. BA food needs to be better. It was just ok. Thanks though to screw and everyone one for safe flight

Crew members were thorough in checking seatbelts and whatnot which makes me feel cared for because passenger safety is a main concern.

I was sent an email that said my card payment was not verified. When I spoke to an agent , he said my card was not verified and the flight I thought I had to booked was no longer available so I booked another flight on another airline(United). Later I got flight updates , etc., concerning my supposed first flight. So if I was charged for this flight on British Airways/American airlines, I need a refund.

The crew made it a great flight. They were friendly and attentive. They made me want to fly British Airways again.

BA has not been handling priority luggage with any special priority. This time our luggage was distinctly very slow to arrive, well after the first half of items to arrive. Business class flights cost a lot and it would be nice to have that reflected in the speed of baggage handling! (I note that this has worsened in our long experience of BA.) On a different note, we spent 2.5 hours on the plane after landing because of an airport mishap at Boston Logan. The pilot provided reasonably frequent update but more could have been done to ensure passenger comfort, such as more beverage and maybe snack services.

Food is horrible. Flight was good and the staff were mostly men.

Delayed suitcase - terrible service to get my suitcase next day, I was informed it would arrive today in the afternoon (Jun/28). Now, I was informed I may or may not receive it until 3 am (Jun/29).

Seats were comfortable, but boarding was the worst I've ever seen. Way too much walking to get onboard as we had to go up & down steps several & then bus took us halfway around the airport for boarding & had to board outside after a very long bus rood.

I will never want to book with these people. They are arrogant and rude. Food was really really bad, crew was even worst

Generally very good. I think their service is better than some other big names I used to travel with. Their food variety is second to none - and you can place order beforehand. Their seating design is a bit awkward for service, I'd say. Flight attendants must be tall enough - long legs and arms - to reach the window seat passenger while crossing over the isle passenger. Also appreciated the variety on entertainment.
