Extremely low quality food. Ordered muslim meals but got vegetarian meals instead. Muslims are not vegetarian, they love meat as much as any other non-vegetarian person, so make a decent effort to get halal meals. Regardless, the vegan sandwich was absolutely tasteless. I am pretty sure the company making that sandwich does not even do a taste test itself

Arriving at Heathrow was a complete disaster because air bridge broke down and it took ages to find spare stairs! Something that I'd kick Heathrow in the shins for, not Finnair - who were great.

Not great. Flight attendants were aloof, food was mediocre, seats that I paid $150 were given to someone else without any concession. I will probably never use kayak again. Terrible experience from start to finish.

The wine was low quality Finnair label stuff in small bottles and only one small bottle each. Embarassinng. A competing airline served me two generous glasses of a nice South African Shiraz from regular wine bottles, a Beck's beer, and a generous Dewar's White Label on the rocks. Cabin service was good and polite, plane interior was beautiful, but cramped.

All good- I love BA and the professionalism of the crew and pilots.

Great flight- smooth, nice crew, nice clean aircraft, departed a little late but arrived 10 early.

It was listed on my ticket as Finnair but there was no indication that the flight was Finnair. In fact the number was even different. There were no employees there until exactly 2 hours before so we had to wait in line at Iberia and hope

Sorting on line would have been appreciated Onward information on flights missed No ability to get seating arranged before we got to gate Very unfriendly at gate

The flight was Finnair but there was no indications anywhere that the checkin was for Finnair also. There was no one to ask. I think at a minimum they should list the code shares so people don’t stand in the wrong line for an hour.

I booked the flight with Finnair, which made the arrangements for downloading a boarding pass unnecessarily complicated. I wouldn't do that again. Instead I'd book direct with AA.

There were issues with the first segment but what really bothered me overall is that you rebooked me and put me in a seat away from my wife and then put her in another booking or boarding group. I don't like having to monitor every little thing you guys do in order to get what I paid for in the first place.

Calgary desperately needs a star alliance lounge in the transborder area for United.

Delays!!! Serious delays. I was told by a member of staff in LGA that I would miss my DEN to LAX flight connection, so I was put on a later flight. Due to delays I would have been able to have made my original flight, where I was sat in business class - seat 1A: I was put on my original flight but bumped from business - 1A to economy 33C. I want a refund for paying business class but only flying economy

Miserable. Active military on orders turned away from Lounge because not in uniform. This is completely contrary to United’s online lounge access policy. Sad that employees aren’t trained better. This is not the United Airlines my parents used to regularly fly with.

Too many canceled flights and kept my wife and I separated on alternate flights. We did not fly out of Denver. We paid a lot of money for the seats we wanted and now that money is gone and we did not sit together. That being said, the many agents were very friendly and did everything possible to help us.

3.5 hour delay known 12-16 hours before departure $15 meal vouchers which did not even cover cost of sandwich. Unable to reach agent for 1.5 hours, only then to be informed any rerouting to my destination would cost an additional $1000. Finally got rebooked on a 7.5 layover in Denver only to find out my original connecting flight was also delayed so I stood by and got on my original connection arriving only 3 hours late instead of 5 hours late. Overall journey was unnecessarily stressful and lenngthy!

When I got our tickets, my husband and I were easily able to get seats together (including a window seat). When we checked in at the airport all the seats were reset and we had to pick new ones, so we couldn’t sit together because there were only middle seats! Ugh that’s the worst. We were back so far we had to check our carry ons which was annoying because I bring an expensive camera that I don’t/cant check so I had to reorganize my items. Once we were seated on the plane we had to wait an hour to take off and they said there was some weather/air traffic in Denver but it was unclear. The lady I sat next to complained that our seats didn’t go back and we both got free complimentary snack boxes which were quite good. I wasn’t going to say anything about the seats, they were the typical uncomfortable kind. It would have been fine if the 2 hr flight hadn’t turned into 3 hrs. Not the best flight but also not the worst.

We love United Premium Plus! So comfortable without the cost of Polaris Club. The crew was so attentive and friendly!!

Horrible, the flights kept delaying, so it is obvious that we won't be able to make it to the next connection. No easier/real agent on site to help you figure this out. UA agent on other counters refuse to assist you and direct us to use the QR code/call customer service. So inefficient and poor. While technology seems convenient, but it's not the best interest/experience for customers need help while there is active issue need assistance.

Not worth the price of premium class ticket paid, felt more like steerage.

We had to be bussed to the plane. And it was raining. Not a pleasant experience.

Good choices were awful. Crew was wonderful to me as I was disabled and they looked after me

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.

If you are looking for the bare bones in an airline - this will do. The boarding process in Newark and Iceland was so disorganized, I thought there was some sort of emergency. No - this is what they do every time. After a full plane was ready to board in Newark, Icelandic Air insisted that everyone have a paper ticket in hand. Mass chaos ensued as dozens of passengers then had to line up in a different queue. On the 5-hour flight, two tiny glasses of water were dispensed. Yes - I could have ordered food, but not even a pretzel was given for free. In Iceland, a full plane of people waited over twenty minutes in a cattle shoot hallway while the plane was readied. Why were we lined up so early? Kids were screaming and some older adults could not stand for that length of time and also hold luggage. Flight was pleasant with the same two glasses of water -one in a tiny paper cup. Movie selection decent but headphones will cost you $5.00. What airline does that? Charge me five dollars more and give them out to passengers. Shame on you for being so cheap!

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.

Food and staff were excellent. Seats on Saga (business class) are comparable to domestic first class of US Airlines, regarding space and recline. Entertainment options had little international component.

Flight delayed Delay to the gate upon arrival Baggage took more than an hour so we missed our connecting!!! Terrible experience!

There is no food without paying $. Only soft drinks are included in your fare.

Some drinks and basic snack will be good. Water should be served at least once an hour. Blankets for folks who might be cold.

Would never fly lauffthabsa again. Seats were way too crowded together....very uncomfortable le

Tickets, paying for bags, and the lack of help by employees was the worst. It took almost 1.5 hours to get this done. The airplane, seating, and stewards were amazing!!! That part of the flight was one of the better flights I have taken.

Very good- my first flight with Airbus A380/800. Some of the food was not tasty , however. Everything else was excellent- the crew, the comfort, the process.

The airplane was as hot as a sauna upon boarding. I was dripping with sweat. Something needs to be done about that.

The airplane did not offer standard outlets so I was unable to work on my laptop. This is totally unacceptable for an international flight.

The smell of vomit from the previous flight was overwhelming for a 9 hour flight. There must be a chemical or product to kill the smell before the next flight boards??!!!

Overall good flight Aircraft is 787 hence seats are very narrow Asian veg food was better than expected International entertainment on screen had very limited choices

Check in and baggage drop was a disaster in both IAD and Frankfurt. It was unclear whether we were to go stand in the Lufthansa line or the United Airlines line. The supposed Service Desk in Frankfurt to get checked in with my 88-year father was chaotic, disorganized and they only offer seating to folks there to get a wheelchair after first making them stand for 30-45 minutes in a line, when seats are right there on the other side of their closed off area. Very frustrating on both ends in the experience.

Boarding process was hectic and unorganized. Delayed for hours, THEN delayed for weather.

No complains with the crew. But generally speaking food is awful, entertainment is not good either.

Entertainment was good. Food was OK. Cab crew was great.

Overall flight experience was good. Unfortunately our process getting to our flight was a hit or miss. Our flight was delayed perhaps for the best as getting from terminal to terminal is very long and security had problems with the machines that delayed us getting to our flight. Heathrow security could care-less that you have a flight you are about to miss!

Horrible. Crew is not helpful. Lounge is sub standard and overcrowded. Getting to your plane is underwhelming “via a bus”. Worst experience I have had.

I had to wait for 10 hours at the airport and no hotel accommodation was provided. That sucks big time.

They can't seem to deliver a delayed bag in less than a week. Is this the 19th century?

We're waiting an BA flight being operated from London to Raleigh

Could be better in all aspects. Poor communication. Rude staff

The seats are comfortable enough, but the layout in business is wacky. The boarding process is disorganized. The flight attendants are friendly enough, but the food and snacks are sub par.

Crew was great. Food definitely top 10% for airline food. Seat was comfortable and legroom was good, BUT the seats were too close together and I was touching arms with the guy next to me the entire flight. Also, I had an aisle seat, and although my arm was pulled right up to my side, I was bumped by passengers and crew at least 6x. I'm looking into business class next time. One last note: the whole British-AA airlines partnership thing was confusing. In 2024 this should be seamless, and passengers shouldn't need this # for BA and that # for AA. There should be a single unified way of messaging from the airlines and checking things for the passengers.

First of all, the flight was delayed. Then at the gate they told me I got upgraded. I told them that if is not a window sit (like the one I purchased already) I am not interested. They still switch me stating: "is more room for the legs". Came to board on airplane to find out is a middle row sit. I explained the stewardess that I have a spine health problem therefore I need a window sit to lean against the wall. She put me to wait by the airplane door till the person who now got my sit will come aboard and if he/she will agree to switch sits then I will get back my window sit. I got lucky that the person agreed. Next was the food. I don't expect restaurant quality meal on a plane, but I do expect to be thoroughly cooked. The green beans in my meal were raw as can be making the meal uneatable. Thank God we got a piece of bread and some butter to last me for the +9 hours flight. Overall, my experience was awful, and I promised myself that even I have to pay more for the ticket I will never fly with British again.
