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

The special need food was awful and gave no alternative.

Our vacation started with horribly, 48hr prior to departure SAS airline cancelled our return flight giving us little to no alternative options.

The Airline was wonderful, passport check at the Copenhagen Airport is a nightmare , coming and going.

Payed $140 xtra for seat arrangement Did not get the preselected seats neiter outbound nor inbound. Absolutely not worth the xtra money

Gate agent in Atlanta refused to let me take my carry-on on the plane even though I met weight and size requirements and the plane was half empty. My ticket clearly stated that I was entitled to one carry-on and one personal item. Will not fly this airline again.

not good missed my connection SAS did not leave me anywhere near enough time to make my connection. Ended up adding about 10 hours to my travel day

I travelled business class with my spouse from ATL to Helsinki and back from Riga to ATL. The seating was not very comfortable. Bread crumbs and left over disposable items from previous passengers were not picked up. The cabin was extremely noisy as the crew keep talking and laughing all night long making it difficult to relax or let alone sleep. Crew must make sure to keep the cabin as quiet as possible. The seating should add a privacy features such as curtain or something. Food choices are limited and average at best. I travel very frequently but this was my first time with SAS. I would try to avoid travelling with SAS in future and would not recommend it to my friends or family. My return flight Aug. 9th was cancelled for no specific given reason or explanation. The new flight on Aug 10th was delayed by 45 mins even though it took off on time. Sorry, if you are disappointed to read my survey but I have to speak the truth. Nayyer Islam, MD

From my last trip nothing except for the luggage fee

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.

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

Worst experience ever. First time and last time with Ryanair. I'm not a cow.
