Great price quality! Bag costs only 15EUR, compared to the 30+ from some other airlines.

Questionary would have N/A available, I did not eat, can't say I'm either sad or happy with that.

budget airline, you get what you pay for but pilots flew great, crew was awesome!

Delays, uncomfortable, and no compensation or free water after being stuck in the plane for more than an hour!

Flight was 1 hour late. The luggages also arrived 45 minutes late.

Ticket desk was really helpful in resolving issues with ticket machine. Reception staff were less than helpful.l and grumpy when issues were highlighted.

The upholstery of our seats (7A+7B) were in bad shape: twisted, hard and uncomfortable. We also had a 55 minutes delay. Apart from that everything was OK.

We arrived on time to our destination and the flight was peaceful (and short!.)

30 minutes late as usual. Could not pay for any food or drinks, despite using three cards. Amex, Mastercard and Visa. Uncomfortable seats

Norwegian ground crew did NOTHING regarding priority boarding. I paid for priority and there was no priority boarding effort made AT ALL at the gate.

I feel SAS is the only airline that does not let you choose your seats when you're checking in, and so we were forced into two middle seats and it was quite uncomfortable. There are not enough new and quality movies available on the entertainment system. After our inbound SAS flight being canceled with less than 12 hours til departure, the whole experience flyign with SAS wasn't great.

My biggest recurring disappointment is that I buy a pre-assihned seat while pucrhasing the ticket and then when checking in it disappeared and I have to buy it again. That's very disappointing and actually a reason I will actively avoid SAS in the future

SAS cancelled my flight SK910 on Sep. 21,2026 because a construction crew from New Jersey Transit accidentally cut through a fiber optic cable which enabled the control tower at Newark Intl. Airport to communicate with all flights. Over 600 flights were cancelled including mine. My boarding code was B2WJMJ, I demand a refund of all monies spent toward this reservation!

More movie options More friendly responds to passengers requests More stops from crew inside airplane

The flight was fully booked very hot and there was no room for hand luggage. I was surprised that there was not much leg room for such tall people. My seat mate barely had room for his hand luggage and had to put his feet and knees in front of my seat. Crew was a bit brash considering a full flight and late departure because of it.

Didn't care much for the food but maybe that's just because I'm American and the food was very European. Would have liked a second alcoholic beverage service in a 7-8 hour flight. I was offered two wines to have with dinner though and should have accepted both. I didn't realize they would only offer alcohol once. Lights were never turned off in the cabin for sleeping. Flight was delayed several hours with zero explanation from SAS. However, the flight attendants were fantastic. We were traveling with a friend who needed oxygen and they were very attentive and helped him throughout the flight. That was greatly appreciated. The pillows and blankets are great. Gift bags with toothbrush etc so nice! This was our first time traveling Premium so alot of perks we were used to getting! The flight was smooth and I loved watching the planes location on the seat screen and being able to watch movies etc. overall it was great I would definitely recommend SAS to anyone and hope to fly with you again sometime.

Food was excellent and plentiful! Cabin crew seemed to truly enjoy their job. Interacted with passengers with a friendly nature. Very pleasant flight

There was no food or entertainment options. Other than buying a beer or soda

The special need food was awful and gave no alternative.

The connection time from the flight to Stockholm and the flight out of Stockholm was too short. Due to a knee injury, I almost missed the second flight. From deplaning at E5 to boarding at F69 takes more than 40 minutes.

Huge wait to board after waiting for 2.5 hours delayed flight

Had no disruptions or delays. Did not order any food.

I liked almost everything (e.g. ease of booking, price, punctuality, efficiency, friendliness, courtesy). A slam landing in Dublin airport took some of the gloss off it, though. Being able to paste here the text of the review of the same flight that I just wrote for Ryanair would make me feel better about Kayak too.

Take off was great but landing is always with a bump.

Staff were very professional. Much better than the outgoing flight from Dublin. Seat cushions were practically non existent. Making for a very uncomfortable flight.

They were extremely unprofessional and unhelpful at check in. They did not understand laws related to Spanish residents flying with family It was very discriminatory the way we were treated.

It's not the staff's fault. The cabin crew do their best but the setup in Stansted Airport by Ryanair is poor. The herding of people like cattle is unacceptable before boarding and is something that's in every airport but only in Stansted have I seen the queueing of passengers outside the plane on the tarmac and the crew only turning up with maybe 5 minutes to depart. This is a resource issue . Yes prices are good but seemingly comes with a price of poor treatment of customers. I'll pay more next time

Flight was fine, crew were good, cabin director spoke far too much; disembarking at Dublin Airport and entry into the terminal building was just dreadful, like entering the back door of a neglected factory building. What an awful impression it must give to first time visitors to Ireland.

all fine - did not have food - there was no entertainment

Delayed delayed delayed and then cancelled very late not allowing for too much time to find a room for the night
