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.

All was good. I think the back of the plane should be boarded first. It would be faster. Minimal waiting time behind passengers loading their carry on baggage.

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.

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.

Old plane with terrible business class seats - good food and service. Boarding was a joke with business class boarding last.

Best airline to travel on a budget- really like their reasonably priced access to the SAS lounges where available.

It was good! Appreciated that it was very on schedule so it made the connecting flight less stressful

I was told we'd have a hot breakfast option in first class, so I chose not get a hot breakfast. It was a very strange meal, but the fresh fruit was very good quality. Service was excellent from ORD to ELP. No service from MBS to ORD, not even water. However, when flying American from FNT to ORD, which is a shorter flight, they at least pass out snacks and offer water.

We were delayed an hour leaving Munich (No fault of the crew). They kept us posted on the status so we knew what was going on, but as a result we missed our connection in Chicago and the communication on connecting flights was pretty poor as we disembarked. It was already stressful and some of that could have been reduced by better communications about where to find transfers, etc.

One problem, but a serious one - the plane is built with electric windows that tint dark to reduce light. Sitting next to the window is VERY UNCOMFORTABLE as it emits so much HEAT in the face when tinted.

The delays (5 hrs) were a comedy of errors, and the multiple safety issues encountered were very concerning.

Wifi wasn't working on one of the UA flights after boarding.

The flight was delayed instead of leaving at 11 it left at 12.20

United WiFi is consistently unusable (it can take 10 mins to load a single web page). If you need Wifi to do work, be prepared to lose half a day of productivity.

Crew was not very helpful. They forgot to serve me coffee and had to wait for a long time.It looked as if they were not very happy with what they were doing.

Good movies, iffy pay WiFi, food ok- on time though and that was great!

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

The transatlantic flight was wonderful. The regional reminded me of jet blue. Crazy and packed. Not enough overhead space and tough on elderly.

All OK. Food, best bring your own. Even a BigMac will be better.

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.

Always find Aer Lingus reliable and good value for money. Food on this flight was pretty basic and the headphone Jack at my seat only worked for one ear. Little disappointed in movie selection, limited on recent releases. Staff are okay - but I always buy a cheap ticket so not like I expect first class opulence anyway!!!

It was cold the whole flight. Luckily had Ski-Jacket with hoodie. The food was just boiled macaroni in 'ketchup'. Better bring your own BigMac. Assisted Boarding was SUPERB!

Great hospitality and service! Seats are better cushioned then some

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

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 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.

I always try to book flights that don’t charge for baggage. Yet I was charged $75 for this flight.

Our flight to Chicago O'Hare was delayed an hour, causing us to miss our connection to MSP and spend an extra 3 hours at O'Hare so we could board a plane with a damaged door and wait another 45 minutes or so. The crew was great, the food decent, The drinks were great: 2 glasses of a nice South African Shiraz, an ice cold can of Beck's Beer, and Dewar's White Label on the rocks.

A350 has great entertainment. Make sure to watch the plane's external tail and nose camera's on landing and take off. Seats were a little hard for a 10 hour flight. I am gluten intolerant, they had good alternative meals for me on the flight.

Boarding was horrible. We were packed into a bus with few seats and made to stand for 10 to 15 minutes, then driven for 5 minutes on wild curves. Complementary food and drink was a tiny chocolate and a bottle of water. Seating was cramped. Aircraft had no video.

didn’t even get to go one of my returning flights cancelled and I wasn’t even in their system, vacation ruined thanks for nothing

Need more time for connecting flights in Munich Food seems worse now on Lufthansa Very uncomfortable seats

Better flight than mum to Frankfurt. But food was very mediocre.

Flight landed on time but land services kept us in the plane for 3 hours. I missed connecting flight.

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.

The flight was good the crew excellent…but take off delayed three hours!!!

Both mine and my husband's chairs were broken. Also it took 2 hours to get our bags after our flight which was wild.

perhaps eye contact with the cabin crew, instead of abruptness and an impatience to serve.
