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

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.

My flight was canceled and we had to beg for united to find us another way home - we were rerouted to Toronto but they never booked us on the final leg back to DC. We had to stay overnight in Toronto, we're now waiting for our flight home and just found out we're on standby and not guaranteed a seat. So yeah, not a great experience with united

The food that was offered based on class level of your ticket was absolutely ridiculous and disgusting. They didn't even hot tea to serve, the food was horrible. On our departure flight I was seated in premium plus economy and considering the cost of the flight the food was literally some of the worst I've ever eaten. On the return flight I sat in economy with extra leg room and was given a thin little throw "blanket" and a flimsy little pillow. The air condition was on artic and the seating arrangement wasn't really worth the money. The seat didn't recline good enough and the foot rest was laughable. Total waste.

I was seated to an oversized overweight person that spread over to my seat. His shoulder overlapped my seat very uncomfortable.

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

Let's just say I won't do it again.

1. No food on a 8 hr flight is a travesty! The fare was not that low. 2. The entertainment was pretty bad and you had to buy headphones!!! 3. Only 2 toilets for the whole Economy section!!

The flight itself was fine, even with a one-hour delay leaving on the Reykjavik tarmac (the lost time was made up during flight). Our experience at the Reykjavik airport on arrival was terrible due mostly to the one hour it took for passport control. Only two stations were open for our category, and the room was full with a huge crowd.

The real reason why the flying experience with Icelandair ---was mediocre was because of not being able to enter DC airspace yesterday evening. This obviously was out of your control and do realize this is a safety issue. I did notice---that everything was being done to get us to Washington Dulles and we did arrive at Dulles SAFELY with just a 4 hour delay. Thank you!

If there was a disclaimer regarding food service or lack thereof, l missed it. If l had known l would have prepared better. Same with transferring at Reykjavik. No information about disembarking via stairs into rain, slush and puddles deep enough to swallow a foot. After being treated to haute cuisine restaurants and warm inviting environment during the flight, the airport is, let’s be kind, disappointing. Plane was comfortable, Airbus, staff were welcoming enough. I would likely try the route again. Maybe have a night and day in Iceland. Maybe not.

For an economy lite experience, it's by far the best I've had. New planes, clean, great destinations. Very happy to have discovered Iceland Air.

did internet check in but still had to get checked in at the counter and this was not the first time. Bummer!

Horrible. I was placed on standby for no reason and they would no allow me to fix the seating into the gate. Plane was hot. Entertainment was abysmal. Seats only take old USB or even older jack plugs — not lightening plugs like all modern phones. Food is pay as you go and awful. Seats were small and uncomfortable. I do not recommend Iceland air.

So Iceland Air is one step above Spirit Airlines. They do not feed you unless you pay for it or are in Saga Class. So, bring your food. They have a drink service, but it's in a large Dixie cup. Ask for the can, that is the only way you'll get a real drink. Also, we missed our connecting flight so they put us up in a flea-bag motel. Don't get me wrong, the staff was nice and friendly, however, there was no shower gel or shampoo in the hotel. We have to go to the corner store to pick some up. The room was not in great shape. Holes in the bathroom, a badly repaired ceiling in the room. The window was warn out. So, you get the just of how bad it was.

Paying $75 for my bag is disgusting. Got off ground late so I missed my connections. Kept us waiting for passengers in the cold. Will not use them again.

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.

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.

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.

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

Based on my wife's damaged condition, BA very kindly upgraded us from cattle to business class. MUCH appreciated!! One of these days, as it gains more experience, BA MAY learn how to depart on time (with over 30 years experience with BA, no flight has EVER managed to leave on time), Once airborne, the entertainment was ever so very pedestrian. But the flight was uneventful and the cabin crew's service was superb. And whichever driver landed the aircraft had obviously done it before. But BA unfortunately is learning from that scuzzy airline Delta. Delta is ALWAYS stunned when one of its aircraft actually turns up anywhere and is NEVER ready to receive it -- even when it turns up where and more or less when it is supposed to, NOT an example worthy of emulation.

Because our ABZ-LHR flight was cancelled by BA for reasons they refuse to tell us--not weather--we did not make this flight and were booked on the following day. BA offered no assistance to us on the phone or in the airport, and we had to find a hotel at Heathrow on our own.

Horrible - flight was delayed by 6 hours - we boarded, were made to de-board due some technical fault; aircraft changed; special meals request on new flight - all went awry. Landed in Dulles airport; breezed thru immigration; as Business Class passengers or baggage was delivered almost 90 minutes after landing; air tags indicated the bags were just near the carousel but the unhelpful BA staff - Maria and Ghina refused to give any update - palming it off on some imaginary invisible “manager” despite air tags evidence showing it right there. So about 50-60 passengers waiting and getting infuriatingly impatient for their bags coz one container was not delivered. Finally after much argument by some other passengers Maria condescended to go to the “ramp” and within 5 minutes the baggage was delivered miraculously. Question is why couldn’t she have done it one hour earlier ? Poor poor experience once again on Business Class BA.

Seating space is appalling. Seats and all surrounding area in "Economy" is built for individuals shorter than 4' 10" and below 120 lbs. Ridiculous. While I'm not expecting fine dining, the food was the worst airplane food that I can recall.

A shout-out to the flight attendent, Lauren, who was the main person assisting me. She was amazing - perfect balance of bright, cheerful, engaging, yet formal

It was good. Couldn’t Check in online and select seats

Check in was not the greatest as had to talk to an agent to clarify things and then he transferred us to another agent who had difficulty processing my credit card as there was a system glitch and not a card error.

I was put into business class. Wow! My flight attendant was great! The food amazing’

Waited 3.25 hours in plane only to have the flight cancelled.
