Reviews of the top 5 airlines flying from London to the United States
Lounge was top notch h with great variety of food and drinks. Cabin crew were great. Smooth flight.
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.
No WiFi, no power to charge phone, confusing boarding, delays
There is a considerable amount of people that use the wheel chair pre boarding along of large groups of family / friends. This is not right should be limited only to the person in need and the airline assistant. Some of these people use overhead bins that do not belong to them. The aircraft had a non functional wifi . The service was bad.
Flight was delayed 3 hours. No food on plane besides snacks
Every thing went smooth. No complaints except deplaning could have been quicker
I was grossly overcharged to change my return flight. Had to do it through Kayak because it was booked that way and I was not given the fare price listed at the time on JetBlue or kayak. Was traveling with another couple that booked directly through JetBlue and they paid the $100 change fee and the difference between what they paid originally(same as me) and the displayed fares and it was less than $400 total for two tickets. I paid almost $700 to change the same fare tickets they purchased and had to pay again for upgraded seat selection that I previously paid for on top of the almost $700 increase. Difficult to talk to the kayak representative because of his accent. Told me I had to wait for confirmation to be sure it had been changed and that I could take up to a few hours. The call itself after the wait time took almost 30 minutes, which could’ve been done directly on JetBlue in 2 to 3 minutes.. My husband and I were given separate boarding zones. They would not let us board together. I had to board in the last zone. They made me check my bag even though my husband told me that he had a spot to put my carry-on. Since he boarded before me. The flight crew tried to accommodate, but the woman that was boarding in the terminal came down and would not let me take my carry-on. She was aggressive, rude and condescending to everybody in line and told them she was being audited. When I told her that my husband had secured a spot for me to put my carry-on with his backpack, that would then move to under the seat. She told me that she couldn’t play favorites, although I was second to last to board the plane since my boarding zone was changed. They told me because I forwarded my husband his ticket that’s what separated our boarding zones, but would not allow us to board together. The volume on my TV would not work, and my upgraded seat would not go into the fully upright position so I was told repeatedly during takeoff and landing to put my chair into the upright position which was embarrassing and uncomfortable to be told assertively so many times. I will not book through kayak again.
Paid relatively a lot of money for a not comfortable seat. I would not take this service again until seating is improved. Food also not up to standard for price paid.
From Edinburgh to Boston was pretty good, actually! From Boston to DCA? Not so much. More food offerings for those w/gluten issues please! I don’t do well w/wheat OR legumes so neither the pasta nor the lentils would have been good for me (or pleasant for those around me on a 6+ hour flight!). Staff on the Boston to DCA leg were brusque compared to those on the other 3 legs of my trip. Also, I paid $19/seat to select 2 seats on the Boston to DC leg and we didn’t get those Row 8 seats but were sat in ROW TWENTY-FIVE😕 Someone owes me $38!
Jetblue provided a very good service during the flight, the plane in a very good condition, the crew is professional, everything was on time. That's it!
The regular feedback of any changes to our flights. The Jetblue staff were very helpful. Our flights were great. Lots of leg room!
We liked the flight, but not in JFK, not in Gatwick it is no lounge and this was surprising and disappointing. I think by now it is understandable that COVID will not go away and why it should not be business lounge?
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
The flight on time, flawless check in and boarding process, the crew was very friendly.
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.
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
Had a plane! Have a plan! Have my luggage! 10 hours of travel turned into 50 hours. Good Lord!
