Really good. Everything went smoothly. That's what I hope for when I'm on a long flight, especially with multiple changes. Thank you SAS.

Really good. Everything went smoothly. That's what I hope for when I'm on a long flight, especially with multiple changes. Thank you SAS.

Terrible customer service. The flight attendants were rude. We experienced significant turbulence for a large portion of the flight and there was very little check in from the flight deck. The space was extremely limited to the point where it felt like torture. Never again

Baggage was mis-handled; food and grocery items in the baggage were damaged.

It was a good flight. Everyone was professional and the flight was smooth.

Service, food was outstanding. They make every effort to make sure that your long flight is as comfortable as possible. The only reason I did not rate them excellent is the way they handled our cancelled flight. They were great about re-booking except for the hotel. A communication breakdown ensued regarding who was booking the hotel for our overnight stay: the city where the flight was cancelled or the city where we were going to lay over for the night. In the end, neither of them did, so we ended up doing it ourselves and were extremely lucky to get a room at all. Given that, I still would not hesitate to fly with them anytime.

No TV screen, free WiFi or power outlets, but seats were comfortable, food and drinks were great, service was awesome!

I experienced trouble with the automatic bag check in. When I scanned the baggage tag I received, things were fine as the conveyor belt moved forward then abruptly stopped! My luggage traveled about 4 feet and I had to reach over a barrier to retrieve it. I went to another scanner position and when I scanned the SAS baggage tag, the screen told me it could not continue!! I went to another scanner position agent who had me put it on the conveyor belt by her & somehow sent it down the belt. I flew from Bergen to Oslo with a two 2️⃣ hour layover before connecting to LHR. My bag was NOT on the flight. I had no clothes for the next day when I flew to Boston. I filed a Lost Bag report and waiting for updates.

When we arrived in Bergen and opened our suitcases, we were shocked! We checked 2 of 3 suitcases and the contents of these 2 suitcases was completely wet!!! It was raining in Oslo and Bergen, but not a hard rain. It seems that someone had gone through our suitcases. There was even sand in the suitcase such that everything had to be laundered when we got to Bergen! We had plastic bags in our suitcases and they had been opened and the interiors of the bags were wet!!! Our valuables were all in our carry-on so nothing was actually stolen. What happened here was unacceptable! There is someone working for Scandinavian Airlines who is not honest and really messed things up for us. Not so sure I would fly SAS again… Marna Skaar

Different airports have different regulations (weight/size) for carry-on.

We arrived at the airport 2 1/2 hours early and barely made our flight due to a 90 minute wait to check our bag

I was pleasantly surprised. I've never flown this airline and the seats were comfy, I couldn't select my seat but luckily got aisle and was able to comfortably sleep the whole trip except when they came around with an in flight free meal, drinks then snack at the end. I'd fly with Aer Lingus again. The only annoying thing is you had to pay for WiFi for different hours of usage but luckily I didn't need it

The embarkation at Dublin was a kin to a Ryanair approach, in other words a circuitous and cheep access

Most narrow seat of my life. Easyjet has larger seats. And as I just wrote in the last comment section - Seat 1A promises luxury after a great businessflight. Instead, it's narrow, the seatbelt is 20cm shorter than the one in 1B, it's just a joke.

No snacks, drinks or coffee. No entertainment, not comfortable seats

This was a great flight. I love the way they had general boarding board from the back first by seat row and in general the flight was very comfortable. The seats were actually comfy, and the food served was surprisingly good.

A seat was broken There was a delay of 45min A checked bag was missing in Boston

The service was some of the worst I have experienced on an international flight. The service was rude, the quality of the food was very low. The speed of service was insanely quick. You couldn’t finish your pretzels before the meal came before the coffee came before trash collection came. Then they never came back for 5 hours. They rushed everything so they could get it over with.

A special shout-out to one of the check-in staff at DUB yesterday noon. We had to use the "Closing Flights" counter and we met, hands down, the most efficient person - able to resolve several issues in the matter of minutes, while remaining polite and calming everyone down. Great job, Aer Lingus!

Air Lingus was in no hurry to get us on the plane as sat at the gate a long time before they boarded us. Then they leave us on the tarmac for an hour. They were no help to let me know what I needed to do to get home. I had to navigate London Heathrow with 0 help from them.

The delay was very discouraging--- having to wait in the airport during the heat wave after a long flight from the US was a challenge.
