Mediocre 2.0

NOTHING.

Cheap flight sounds great...except it’s not actually cheap. Once you add on charges for baggage, seats, water on board, etc., it’s about the price of a standard ticket on a quality airline. (Plus they didn’t actually reserve the seats I paid $20 for, even though I have the receipt). Amenities on board are atrocious. No Wifi, no in flight entertainment (except an iPad you can pay $25 for that features 10 movies from 1992), no USB ports...you even have to pay for water!!! My flight was delayed twice in one week causing me to miss my connecting flights both to my destination and back home by 5 minutes. Because they are not a member of an airline alliance, my only options were to wait until the next day and stay in a shared hotel room or rebook on another airline for $600 which they couldn’t guarantee I would be reimbursed for. The general apathy shown by the staff and lack of communication is abhorrent. The least they could do is apologize and help direct me to somewhere I could find more information. They were positively clueless! Spend a little extra and book on a respectable airline that values their customers...and maybe you won’t be out $1200 (in addition to the cost of the “cheap” tickets) like I am!!

Flight was ok

The flight was actually run by turkish airlines, not philippine air as stated in my confirmation email, so we were sent to the wrong terminal. Nothing in the email said which terminal the flight would depart from or that it was actually turkish airlines. Very irresponsible and communication for customers should be much clearer. Luckily we were very early for the flight or it could have caused a serious problem.

This has nothing directly with SAS, but since I experienced it during my flight there, they are responsible of it. I was waiting for the flight at the OSLO airport waiting for the flight to LONDON. I had ample time to work on my computer. In the big room by the gate there was only one spot where I found three electrical sockets hanging from a pillar or post. To my dismay none worked. My plug would fall off from each. To document, I took the pictures of the useless sockets... I complained to the lady at the boarding desk (she left before the SAS staff moved in), she did not even care... This experience frustrated me and turned an otherwise pleasant trip into a bitter one. Please install some working sockets in your waiting room!

More comfortable seats for long haul flights is a must have. Comfort+ Offered a money’s worth alternative to business or first class. Boarding is done away from terminal building which required busess for transportation back and forth. Prefer skybridge instead.

This is obviously a very well-run airline. Boarding was efficient, the crew were warm and professional, and the overall feel of the aircraft was very Scandinavian-cool. I was most impressed with the meal service. We were served twice on our 9 hour flight, and both meals were hot, healthy, and the best I’ve had during a flight. The passenger in front of us was having a hard time with her sinuses, and the flight attendant (whose name I wish we had gotten) was very attentive and concerned for the comfort and well-being of the passenger. She insisted on doing anything she could to alleviate the woman’s difficulty. It is clear that the crew care about the passengers’ experience.

We were unable to sleep at all during our overnight flight and landed pretty exhausted. Our seats were comfortable (complete with a moldable headrest to keep your head from bobbing around) but we felt too upright to fall asleep. The passenger in front of us reclined, but we were concerned about reclining into the already tight space of the passenger behind us. So we weren’t able to sleep, despite trying to get comfortable/somewhat horizontal. It seemed to be a mixed bag of asleep and awake passengers on the flight, so some people were unaffected by this issue.

Prices are per person and are for e–tickets and include all taxes & fees in USD.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller.
At KAYAK we don’t set the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find, on occasion, that certain prices are no longer available.

If you have more questions or if you have a bad price to report to us,
please send us an and someone from our team will get back to you promptly.
