Find cheap flights from London Heathrow Airport to United States

Pros: Crew super!! Entertainment very good

Cons: Plane excellent condition and super clean. Take off and landing on time

Pros: La atención de la tripulación es la mejor que he visto. El servicio de alimentación es muy bueno.

Pros: They were very nice! Always a smile, even after 10 hours with us!

Cons: Final snack was a ricotta pepper sandwich - which was kind of a weird choice. Kitkat was of course delicious. Beef stew for lunch was fine. but my meal come out with frost on it, so the salad was freezer burned and my dressing was unable to pour being frozen! no veggies for me! :)

Pros: Friendly, quick and efficient crew! Great food too!! My favorite part when in Houston, Texas my starting point, was that I never had to do the self check in, y’all actually had “real” people going the job!!

Cons: Boarding in order, by the seat numbers. That’s the only thing y’all can improve on. It was my first time booking with Lufthansa, and I will definitely book with y’all again.

Pros: Staff were professional and polite.

Cons: Despite zone boarding, boarding and disembarkation were very slow. Passengers like me with flight connections were very anxious regarding missing these.

Cons: Keep the temperature at a more reasonable level. Blankets + two layers of clothing was definitely not enough.

Cons: Seats in economy section are very close together . There is not enough room for knees...especially for such a long trip.

Cons: Boarding was crazy. Could not everyone in the gate area.

Cons: i was somehow ‘offloaded’ from a seat that i paid extra for.

Cons: 1 hour delay due to maintenance but the ground crew and pilot kept us informed.

Cons: Flight delayed by over 4 hours. Took another flight

Cons: United Boarding is ridiculous run out of overhead space passegers apparently don’t know how to use overhead space even a mess I fly 50+ times a year this was worst

Pros: Crew was great !!!

Cons: Seating in upper class is uncomfortable and bedding is not fresh.

Cons: Very uncomfortable seats, food was bad

Pros: Very friendly crew. We boarded about an hour before so we were ready to go well before time.

Cons: The economy seats are not that comfortable and the screen for entertainment is sometimes difficult to use.

Pros: Service and food are good. Crew very friendly and tries to please everyone.

Cons: Chair could be more comfortable compared to other seats who transform without turning over. Still - much much better than BA.

Pros: Crew were very good.

Cons: No vegan food available.

Pros: Crew asked us if we’d like to move to an empty row to be more comfortable without us even requesting it.

Cons: Bigger coffee cups? Really nothing to complain about. Everything I would expect from a flight. A++

Pros: n/a

Cons: The conditions were very cramped. The entertainment system was quite old and had very little selection. My entertainment system actually stopped working all together. I called for assistance from my seat a couple of times, but nobody came.

Pros: I loved the different features on the screen and the excellent. Customer service on this flights

Cons: The space on the seat.

Pros: The crew had an amazing personality. They definitely enhanced my experience

Cons: Nothing

Pros: The boarding was great and moved very well. The crew super friendly and helpful.

Cons: More information on how to use the complimentary Wifi in the cabin. I had the app and it helped me but it’s not immediately in front of you so the passenger can decide. You guys offer WiFi in packages and most of the other airlines do not.

Pros: On time

Pros: The atl to bwi leg was not great. No inflight entertainment and the aircraft looked old.

Cons: A newer aircraft that doesn't show its age would be nice

Pros: The complementary wine was nice. The raspberry sponge cake was nice. Nice options for entertainment.

Cons: No one in the entire airport knew what flight I was talking about when I told them it was Iberia + flight number. People were saying I must have the wrong airport. I almost missed my flight because of this. Everything was through American airlines. It would have been nice to know this going in. Also it was tough doing transfers because once again, none of the departure screens refer to "Iberia flights." It was also tough to check-in. Instructions were not clear in terms of the booking number to use. The Iberia app had a lot of usability problems. The seats are too cramped. I'd have to take out a loan to be able to afford business class or 1st class. It's absolutely horrible for everyone in coach. Especially for long flights as this one. The food was subpar, but that is to be expected in my opinion. Would have been nice to offer complementary headphones. I wasn't able to utilize the entertainment because my headphones are blue tooth. Upon arrival, we had to sit on the tarmac for 20 minutes because there was another airplane in our spot.

Pros: Boarding was good only because I skipped to the head of the line to get all the way to the back of the plane without having to wait in the aisles for others to get situated or hold anyone up (as no one was going further back than I). Staff was pleasant, did what they could with what they had. I was very happy that the back of the plane was not very full and I was able to lie down on the floor to nap for a couple of hours.

Cons: Entertainment was miserable. Not much to look at on the screen and the sound quality was so miserable that I could not enjoy the decent classical selections. I was frustrated by the merry-go-round visual of our plane en route to our destination and wished I could have gotten the simple clear images that were being shown at the front of our cabin. I am sorry that the only vegetarian meal is Asian, as some Asian spices give me a belly ache.

Pros: Great crew

Cons: WiFi not working

Pros: Nothing to complain about. A nice, calm trip.

Cons: It would have been nice if members of my group could have flown together instead of being scattered around the airplane.

Cons: The people working on the land side lack of a complete sense of service. They are rude, unrespectful and with no professionalism. It is a shame that the last impression you get from Israel is the aggressiveness.

Cons: We had to check our bags because the plane was too full, this was inconvenient and it made the plane arrive a little late

Pros: The onboard store.

Cons: USB ports. They were off.

Cons: They lost my suitcase

Cons: The flight was delayed by 3 hours making me late for the next two flights and ultimately costing me an entire day longer in transit. While I understand these things happen, Air Canada's response to me asking for help was abysmal. Ultimately, they didn't care and told me it was my problem. Sadly, one of the first people I talked to really did want to help and arranged flights that would have gotten me back on track but he was prevented from confirming the changes due to management. I will never fly with Air Canada ever again.

Cons: AC lost one of our suitcases and it did not arrive until late afternoon of the next day. Filled out a missing luggage report.

Cons: I’m just thankful the Castlegar flight went.

Pros: The crew that greeted us (and sorted out seats) was excellent.

Cons: We had booked seats together two months before our trip; when we checked in (both legs are Star Alliance, but Air Canada—one leg both directions—did not allow any on-line seat choice or changes), we had been separated to different rows altogether (and since it took two Air Canada trips to get from Vancouver to Denver; the first had mechanical difficulties an hour into the trip and had to return), and there was no way to change it online or at the airport.

Pros: Food was better than I thought it was going to be (not that I have enormous expectations for airline food, but it was quite good).

Cons: Economy class is cramped, and it was a packed flight. Obviously, this is not a BA-only issue. It may have been me in my dehydrated state, but the cabin was also quite a bit warm.

Pros: I slept. Pillow, blanket, clean disposable headrest cover Food was decent Way above average crew.

Cons: Long boarding process. Broken headphone jack.

Pros: Ran into some turbulence and the pilot did a great job calming down the passengers and explain the weather situation.

Cons: food option were limited, only one meal choice left

Pros: Crew was exceptionally friendly.

Cons: Entertainment units often malfunction. Seats are cramped.

Cons: Service very cold and rare to find. For some reason finnair doesn’t announce boarding

Pros: Of all the flights I checked this was the most convenient in timely manner and comfortable.

Cons: Movie options.

Cons: - Leave in time - Working onboard entertainment system

Pros: Everything was nice.

Cons: Nothing to complain about.

Pros: We liked that the boarding process seemed to have been streamlined and organized from other flights (this was a UNITED flight which we flew through Austrian Airlines). It was efficiently done. We thought the selection of movies to watch were terrific. So glad to have caught up on several I had wanted to see. Considering we had a 3 hour delay, I got to catch up on ALL the movies I wanted to watch!

Cons: The plane was delayed just over 3 hours by a mechanical problem with the radar. We taxied to a remote gate while they tried to fix it. Original estimates were an hour, but it ended up being 3 hours. We stayed onboard which was probably best in this case - but having been trapped by United on a flight many years ago from 4 pm until midnight with 3 small children and then told to come back at 7 am the next day - I am very wary of the airline now and actually drive from Washington to Chicago as we could have done that in the time they trapped us! This flight was practically empty however, so unlike many transatlantic flights, we could spread out and were more comfortable than usual. So that was lucky for United otherwise my scores might have been a LOT worse! Also, we hadn't eaten, figuring that we would eat dinner on the flight. So after 3 hours we were a bit peckish! The crew came around with a cookie and water. Really think that might have been a little more especially considering the flight had so few passengers. So we arrived back in DC just about 10 pm and, after clearing customs and getting bags, were home to Arlington about midnight - 5 am our time! Given the conditions and circumstances, the crew did a good job. I would like to think that Austrian Airlines would have some input with United. The outbound daytime flight from Washington to London had been simply terrific with a wonderful crew - new to the route I think. They gave as pointers as to what we were seeing out the window, which we always appreciate. Just as my daughter wondered what we were seeing out the window, the captain would tell us. So in short, the outbound flight was in a different league to the return flight. But that's down to United and not Austrian Airlines. And these things happen and I'm glad we didn't have to change planes or make other plans.

Cons: To arrive on time.

Cons: Buses to and from the plane. One driver left us in a full bus waiting for 20 minutes. When we arrived in Vienna, there was no bus to pick us up. We had to wait in the plane until one showed up.

Pros: Professional crew

Cons: Depart on time

Pros: It was Okay

Cons: I m disappointed with the online deal I have booked my self with two checked bags & paid extra for that but I had to pay £ 80/-

Pros: It was on time and everything went well

Cons: They could have offered more water

Pros: The crew was super nice. Everything went smoothly.

Cons: My gluten free meal had a carrot cake... the first ingredient was Wheat! If you have any type of allergy do not trust their food!

Pros: Sleeping and being left alone

Cons: Food, Service by cabin crew because they never smiled

Cons: At least give a glass of water.

Pros: It was just a flight. Nothing to rave about. Just a typical up and over flight. The flight left Athens over an hour late and got to Brussels almost 90mins late.

Cons: We weren't offered complimentary beverage service. They did a beverage service for paid drinks and that took well over an hour. We were only given a simple single piece of chocolate while waiting to take off

Cons: Flight keft 35 min kate and boarfing was very slow and disorganized

Pros: Very efficient.

Cons: Better airflow in cabin, letting you know about meals before getting to plane.

Pros: Food and beverage choices excellent

Pros: The staff were helpful. The entertainment had good variety. Adjustable head rest was useful.

Cons: The seat was a little lumpy. More leg room would always be appreciated.

Pros: It was a great flight!

Cons: nothing, pretty much perfect!

Pros: Quite a big choice of movies and TV shows to watch, more than enough for an eight hour flight. Normal headphone plugs so you can use your own.

Cons: I booked together with my wife, yet we were allocated seats apart and were not able to be reassigned together. The leg room was so tight that I could not pick up things off the floor without putting my head in the next persons lap. Though the cabin crew were smiley and friendly, it was hard to get their attention when needed. The PA system is much louder than the entertainment, so announcements were ear bursting. The dinner selections ran out early, so a good proportion did not get their choice.

Cons: When a bought my ticket, I had asked in the office about WiFi. They told me that you have WiFi on the plane. I had checked this information on KLM.com and saw the same, that you have WiFi. This was the reason, why a chose KLM! Then I tried to connected on board but I couldn’t! WiFi was not available. Crew told me that they don’t know anything about it! I was disappointed and angry.

Cons: Boarding at Florence is always chaotic but this isn't within the control of KLM or their crew.

Pros: The pilot and the crews were helpful about the transit. Pilot make up a lot of time.

Cons: Flight was delayed, had to run to my next connection flight.

Pros: Great atmosphere, crew was excellent!

Cons: I’m 6’5”, so legroom can always be a complaint, but this wasn’t too bad. The plane appeared to be fairly old and didn’t have WiFi. Entertainment also was on an older screen which was navigated by using an old in-seat phone.

Pros: Great crew who were prompt with service and friendly!!

Cons: Notjing

Cons: Very little legroom.

Cons: Too short a connection between flights. Missed connection. No priority for those with connecting flights. No customer service to ensure passengers know which gates to go through and if passenger has chance of making flight. No recognition of time it takes to get through customs and security to make connecting flight. Actually any semblance of customer service was lacking for passengers to make connecting flights.

Pros: Plane ride was very smooth. I was particular about the type of plane. Fly-by-wire planes(mostly built by Airbus) tend to be smooth sailing

Cons: The back of the seat should have better storage. Was not good at all. Some flight attendants efficient but not friendly.

Pros: New seats are excellent

Pros: Incredibly nice staff, new aircraft and lots of room and very clean airplane

Cons: Food :) maybe include a vegetarian option for the sandwich snack

Cons: This was actually a United flight. It is very confusing when all of the travel documents I received from Kayak show Austrian Airlines yet when I get to the airport to check in, it's United Airlines.

Pros: I like the room spacing of seats and it wasn't over crowded, it was clean and the flight attendants were very friendly. I could not asked for a more comfortable seat being in economy seating.

Cons: I have no complaints I truly felt comfortable and safe.

Pros: Crew was attentive.

Cons: Tiny, uncomfortable seats with warn cushions.

Pros: The staff were helpful. The entertainment had good variety. Adjustable head rest was useful.

Cons: The seat was a little lumpy. More leg room would always be appreciated.

Pros: Entertainment and helpful staff

Cons: Had worst seat on plane on outward because I didn't know I could pick a seat free of charge before online checkin This could be a lack of communication on Kayak/Last Minute.com as opposed to Virgin

Pros: Everything was easy

Cons: Business class seats are snug for big people compared to other airlines

Pros: Good amount of space on the plane, lots of movies to watch, good food and drink.

Pros: Decent price for economy comfort seat, 4A.

Cons: The flight was delayed about 80 minutes and they did not informed until when I got to the Airport. I could have stayed more at home instead of the terminal. They have also changed the boarding gate..

Cons: All positive.

Pros: The socks offered in business were comfortable and nice looking. The red wine was good.

Cons: The food was just average and the seat not too comfortable
