Reviews of the top 5 airlines serving from London to the United States
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
When checking our bags at the Virgin Atlantic counter, the employee told us that we should go to Delta because we needed to verify our passports and our names. Fortunately the employee organizing the line stopped us and asked why we didn't hand over our suitcases. He sent us to another line and told the employee that we already have the passports verified in the reservation. She understood and received our suitcases. In London they have a general waiting room, where you stay until the gate number of your flight is announced. KAYAK informed us the gate number hours before the airlines did. Just like the flight to London, the legroom is too small. abusive for a flight of so many hours.
Bathroom broke, had to rush to board because of late exit of previous flight
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
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
The friendly staff. They kept time. Was suprised to get some drinks.
Didn’t know you had to pay for earbuds and food on flight. Sounds awesome and better way to not waste food or items. Comfort of flight is was amazing other than that
I was not expecting having to pay for headphones, water and basic food in a 9 hours flight. Price for this flight was as high as any other, still I had to pay 4 lbs for a can of sprite. On top of that flight attendance gave a bothered look when I asked her for some ice for my soda. She reluctantly when to get it, brought me literally 3 cubes and walked away without looking at me to avoid another request. I couldn’t believe it. She was soooo rude. I will never book on Norse again and I will let everyone I know about this. Unforgivable, very bad customer service.
Great crew. Customer support is pretty much non existent. I had 2 tickets that were not used, the flight was overbooked. I think I should have been reimbursed for the unused tickets.
Why call us to board if we’re going to be made to stand in the tunnel for 20 minutes. Really hard for people with little children. Plus it took me ages to check in because my seat in Premium was overbooked so I didn’t actually have a seat. I did end up receiving my seat in Premium but there was a lot of stress and confusion beforehand. Hope is it possible to overbook seats? Especially in Premium!
We flew one way from Gatwick, London to JFK NY For 2 people $1200 and no food offered not even water. You had to buy food. Norse advertises as a low fare transatlantic airline, they may want rethink that. Crew, flight was fine. Ironically we flew American from JFK to Heathrow for $1000 (2people) and included food and drinks.
We flew premium on the way TO London but went back to economy for this flight. The differences I note here may be colored by changing service. The crew was professional and polite but cold on this flight and class of service. They seemed to want to have as little to do with us as possible, beyond providing the basic services in economy. The aircraft was still good though, and the pitch was about as tight as expected - manageable but no extra personal space to spare. Overall I would certainly fly Norse Atlantic again, given the opportunity.
I loved the ability to upgrade my seat which was worth it. The large seat and ability to recline made it comfortable to fall asleep. My only two complaints were entertainment (movie selections were old) and approx 30 mins before landing the crew started to collect the blankets despite the cabin air temperature remaining cold. Maybe wait for passengers to get off the plane before collecting the blankets.
Very much dislike: Airline requires check-in at the Airport Airline does not work with TSA PreCheck
The crew was unfriendly front check-in. The filth in the plane was so disappointing. I could smell dirt and looked up and there was literally dirt that was blowing in through the air. Old food on the seat back tray in front of me so I didn’t use it. No toilet paper in the bathroom and scum/old dirt next to the seats.
one meal and one breakfast or sandwich instead of two meals.
Many issues arose with the plane and after 3 hours of delays, we had to return to the London airport as the plane was unfit to cross the ocean. It was highly concerning that this aircraft was in operation with so many problems.
You're asking 2 different questions. The flight from Los Angeles to London (and from London to Faro) was on British Airways. Those flights were awful. The app didn't provide detailed information, the WiFi that I paid for didn't work, the form I had to fill out to re-enter the UK was not communicated clearly so I nearly missed my flight. British Airways is significantly behind every other airline I've traveled in every way. American Airlines flight form London to Los Angeles was great. In the future, I will avoid flying British Airways when I can.
Premium economy was not what was shown, no leg riser, seats were broken and do not recline more than economy, food, we couldn't eat it was so bad, no menu 1 item and it sucked.
British Airways is very good... Taxiing after landing took 35 minutes, can't really blame the airline but the terrible infrastructure at JFK.
Our section of the aircraft in premium economy was very cold. We asked the attendants twice to raise the heat but it never happened. Even with the blanket it was chilly for 10 1/2 hours
Because kayak scammed me with false advertisement saying 23kg was included but I ended up having to pay another £200
The flight was canceled and I was directed to Air France two days later than my plan departure day. This involve getting two more days of hotel and also not being able to get a boarding pass until I got to the Istanbul Air France boarding desk. It has been a troubling time.
It makes no sense for several types of drinks to already be out of stock in the middle of the flight.
I have a walker I need it to get from the plane to customs and baggage claim. It had a huge orange tag on it saying it should be given to me as I got off the plane. It was not and the flight staff didn’t know where it was—both on my flight to London and on the return. In It was very frustrating
