Bathrooms weren’t too clean. Onboard entertainment was light. Other than that everything was great. Food, service, comfort and crew. Although it was hard to understand the crew announcements.

Bathrooms weren’t too clean. Onboard entertainment was light. Other than that everything was great. Food, service, comfort and crew. Although it was hard to understand the crew announcements.

My return flight has been changed to JFK from EWR without any notice or reason

This was my first time flying SAS and used them for 4 flights. The crews, flight and communication was outstanding. I flew premium economy and was extremely impressed by their SAS lounges. I will 100% ise SAS again. Everyone was so pleasant!

I upgraded to economy plus and it’s so worth the price. The crew is exceptional and the food is pretty decent. I would definitely fly with them again.

They lost my luggage. Tromso in winter without warm clothes is not fun.

I paid for wifi and it worked about a total of 5 min. Feel ripped off

I couldn’t make it to the airport for my original flight due to bad weather; roads were shut down, buses and trains were closed. Since the plane wasn’t cancelled, I still had to pay $720 to change my ticket.

Overall, this flight team did a fantastic job. They came often with the water, coffee and tea. There was no meal choice in coach, but the lasagna lunch was decent. The sandwich snack just before landing was tasty. The baggage bins were large, so no trouble holding carry on luggage.

Good friendly service and food - The seats in business class are old, too hard and not very comfortable.

My seat was not the one I paid for, the crew was very curt, and the cabin was extremely warm.

Food quality is deteriorating each time, last year was very good. I avoid the plane food lately.

Been flying on various airlines, all over the world, for 50+ years. The food on Brussels Air was easily the worst I ever endured.

I like the frequent mails we get when there is an update. Please keep it up

I have traveled to probably over a hundred locations worldwide, but had only one mixup of airport in Shanghai. Until Iceland and Stockholm. Reykjavik has 2 airports, Stockholm 4 (!). Please indicate clearly when a departure flight is scheduled from an aiport other than the international aiport. That would greatly reduce stress. Thanks

More than one hour detail with no explanation and no compensation

my husband's monitor did not work. there was a visibly ill family in my husband's row.

we had to unexpectedly check a bag, the flight was late getting in

There was a two hour delay because of incompetence in scheduling fuel truck. Further, upon arrival in Roanoke, hand baggage was sent to baggage claim. We carry hand baggage because it contains valuable or sensitive materials that we do not want going through the baggage system. This is very poor and United needs to perform better.

Pros: "UP TO THE MARK I EXPECTED"
Cons: "A PILLOW WOULD BE GOOD, MAKING THE FLIGHT MORE COMFORTABLE"
Pros: "the only thing that stands out was the agent who checked me in at Entebbe. She was pleasant and helpful. Most things were ok, but not special."
Cons: "Because I require oxygen onboard, I was not allowed to check in on line. consequently, my wife and I got middle seats that were very tight. At least one of them was an aisle."

the room on the plane was good but that is because flight not sold the other three seat and I had room. the food in terrible.

First the price I paid was excellent, my flight was full, but my seat was roomy. The one downside to the experience was they had games on the entertainment console. The guy behind me poked at my head about half the flight. I hope they get rid of this feature.

They should. Heck planes more often not when they are suppose to be leaving causing delays

Flightl was good and on time. Only problem was the quality of the air in the cabin,didn’t appear to be clearing the air circulation.

Crew was fantastic got lovely food and plenty of water. Entertainment was good. Never had to ask for anything. Left on time and got to Seattle early. Luggage did not take long either.

Great hospitality and service! Seats are better cushioned then some

Great hospitality and service! Seats could always be cushioned better.

Excellent long haul experience really enjoyed using Dublin pre-immigration

Nice easy flight. Crew was very nice and of all the times I have bought a seat for my guitar - this was the easiest. They were prepared and no problems at all.

The only issue I had on this long flight was that when the stewardess would come over the speaker, which was several times due to turbulence, it came into our earphones so loud as opposed to just being in a normal volume it made me jump and wake up. Others around me were also commenting on this issue.

The bad part was 2 hour delay and we were seating in the airplane it was getting hot and uncomfortable But after they fixed the problem everything went so smooth Crew were amazing very nice polite and caring

Touchscreens do not work. WiFi did not work. Food is possibly the worst on any European airline. Drinks came by only four times on a cross-Atlantic. The plane was two hours late because—it was announced—Lufthansa didn't have enough large aircraft in their fleet to accommodate an on-time flight.

It was freezing in the airplane. Everyone was wearing everything they had with them. The crew acknowledged it was cold, but did nothing about it

The flight attendants were superb and the service was outstanding. Some passengers with small children were very rude and inconsiderate, kids were constantly crying and some were running around the aisle unsupervised.

Terrible. There was a rattling noise the whole flight. The internet didn't work after I paid. Boarding is very disorganized.

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!

The crew member put her luggage and boxes behind my seat so I was able to recline while the passenger in front of me did for 8 hours. My knees were forced against the seat for hours :(. Dude sitting next to me hasn't showered in weeks so I almost threw up.

Sorry my last review for prg to fra was for this flight. My prg to fra flight was fine but my second flight back to Washington DC was with a slow awful crew who wouldn’t come in a timely manner to take trash and take trash before serving coffee tea and was shoving other people’s bottles of water on me when we were not traveling together

Lufthansa was amazing. Definitely upgrade your seat if you can swing it - they take very good care of their passengers. Customs in DC is nothing short of a nightmare though. Stood in line waiting to go back through security for 30 minutes, had to RUN through and across two terminals to make my connection and only had 5 minutes to spare. Terrible. Very very poor coordination by the airport staff and CBP.

I was ver pleased with the service all the way through

I would have preferred something lighter for the second meal. Maybe a small sandwich .

They cancelled our flight the morning of departure at 4:30am.

Coach seats are too tight. Seem designed for small people. Food different but OK. Staff helpful.

my original flight was cancelled the previous day, and i was rescheduled onto this flight, which left much earlier in the morning, impacting my previous evening and requiring me to get up much earlier in the morning to get to the airport online. This practice happens way way way too much, and it seems on every airline, though AA is probably the worst.

Spending 10 hours on a flight with no video or wifi access due to issues per stewardess was not enjoyable nor acceptable. Will follow up directly with the airline as well

I really did not like being ordered to pull my shade down by the attendants. One of them was very rude to me about it, standing there until I closed it like I was a child brusquely reaching across me to close an adjoining one. They claim it was so people who wanted to could sleep. It’s a 10:30am flight not a red eye. Closing your shade or leaving it up for natural light should be a choice. Ruined my flight!

My baggage did not arrived with me. Took 3 days to get it after so may calls and follow up

The crew was very attentive and kept busy serving a variety of treats!

Terrible. Flight was 3 hours delayed and I missed my other flight to my final destination

Offered vegetable curry when it was actually tofu which I don’t care for.
