Amazing, delta One is extraordinary. Worth the money. They took our bags at the door when our driver dropped Us off at Heathrow.. the Virgin CLUBHOUSE lounge was wonderful and the flight was great. Service food our little pod all near perfect.

Crew members were nice and professional. TV, you have to press very hard on the screen to get it to respond and WiFi didn’t work. Overall okay flight

Crew and support were very good; lounge was very good. Seat was narrow and very close to other passengers; lie flat is more complicated and exposed to the aisleways.

London to Atlanta was good. Atlanta to Phoenix was not. Poor boarding as I had to check my rollerboard even though there was plenty of room in the bins. Crew seemed inexperienced. Sat just off the gate for nearly 30 minutes with no explanation from the pilot while the cabin got hot. I typically have a much better experience with Delta.

Wonderful crew, great movie selection and good food. I prefer Airbus to Boeing, much more comfortable

I wish the inflight entertainment system options were broader, but overall this was a fantastic crew and I can’t express how cheerful, welcoming, and attentive they were.

Flight was operated by Virgin Atlantic and it was up to their usual high standard. Minor grips about some issues, but they are really first world issues and as a whole, was an excellent flight.

I paid for a business class ticket on Delta. It was sourced to Virgin Atlantic. They changed out the aircraft which had fewer upper class tickets. Even though I'd checked into the lounge, was receiving alerts via kayak about the delay and changes; no one informed me that the seat would be changed - until I attempted to board and was told that I would have an economy seat or they could search to put me on another airline. Even the flight crew were informed of this change (10 passengers were bumped out of Upper Class) around 2 pm (1400) time. Hours would have helped to consider alternatives instead of making a last minute change. There needs to be compensation from both Delta and Virgin given this change in service/experience.

Movie selection was meh. Food was great. Crew as always great. I paid for premium because that’s the only way not to feel like a sardine. That’s how economy should be imo. Sadly passengers have to pay an extra $1000 to get what they should at base price but that’s all airlines. The airline industry in general treats passengers as cargo.

Ongoing flight was delayed. Staff at bag recheck was able to get us on an earlier flight. With only 20 minutes till take off we feared our bags would not make the new earlier flight. We were most delighted that they did and were there when we landed. Delta came through

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

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

Your food is AWEFUL! For Premium Economy this was the WORST FOOD EVER - salad and tomatoes were all spoiled, "chicken" was awful and burnt. This is the WORST FOOD of ANY AIRLINE!!!!!!!!!!!!!!! horrible

After flying on Icelandair to England and getting a greeting glass of champagne, free drinks and salmon I returned to the US on United for around the same price and got told immediately that I would have to eat a vegetarian meal because everything else was gone and every time I paused thinking in flight entertainment I got advertisements on the screen. On the Icelandair flight I had a great selection of documentary films and on United I was reduced to watching the Spider-Man movie. Guest which airline I look forward to flying again?

As always, Lufthansa checked my carry-on luggage, even though I was in front of the line. No other airline in the world does this. It's so annoying and unnecessary. There was enough space for it in the overhead bin. It's a TUMI Continental Carry-On. If you have the chance, rather fly easyJet or Condor on this route.

Someone sat in my seat and this made boarding protracted and unpleasant. The stewardesses kept saying, “it is important that everyone be seated — or we will be further delayed,” but for a long time they did not tell me where to sit. At the end of the flight a baby screamed loudly for several minutes and it took ninety minutes (!) to get through EU passport and customs. We had to stand the whole time in a an overheated room. The seat on the plane was narrow. These things are not all Lufthansa’s fault but they made for a somewhat unpleasant trip.

Everything about the flight was excellent except for the fact that we had to wait one hour on the tar app and then I had to race to catch my connecting flight with the next stop

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.

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.

My inflight entertainment unit was not working. The chair compartments were broken. The suite door would not latch. Given the cost of the total ticket, I was extremely disappointed in the service. The flight crew was not very helpful.

7 hours is a very long flight - the crew was ever present and helpful. The cabin was comfortable - WiFi was a disaster as was the entire entertainment and flight info system. They could have helped passengers by explaining that the information available on our screens and our continued attempts to entertain ourselves with our phones would be in vain. Other than that - all was well! Very comfortable seats, amenities galore and lots of crew attention. They might have benefitted from more crew as very few served the premium and basic economy,

The boarding area was crowded with inadequate seating. Flight delayed which made it uncomfortable.

Terrible we had to wait out in the cold for transfer bus to take us to the plane. Once we finally got on the plane seat had no cushioning not comfortable at all. Food was overcooked and dried out. I was skipped over when they served drinks I had to call them back to give me a drink with my food. Overall terrible experience this time. I have used BA before and never experienced service like this before. If this keeps up I will look for other options

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.

Cabin crew was very good. No wifi and no doors to the suites

Would not let me board with my fragile guitar so had to check it in. Who knows what the icicles did to it. Not happy. Had to run to catch my connection in Heathrow. After a bus and a train? Was asked by a guy in the middle seat to change my window seat with his girlfriend's middle seat further up in the plane and I was insulted. What nerve! The food was unhealthy and the seat was cramped. Could not wait to exit.

need more US friendly food options. Directions on getting to the next gate were terrible - resulted in long walks to the terminal and then finding I couldn;t enter there and had long walk back, then train to security then train back to where I started in the first place
