My flight was canceled for no reason. I am currently stuck in Oslo for the next 4 hours waiting to go to Berlin.

The cost of the ticket was perfect, very affordable. I didn’t have a meal included, but was surprised that I was never even offered water worth the other passengers as attendants went down the aisle. I was completely looked over.

I was VERY surprised to witness such unfriendly, mannered attendants. No smiles. No excuse mes or sorry when bumping in to someone or needing to get by. I felt like I would’ve put them out too much to ask for ANYTHING.

I have traveled with different airlines such as Delta, France and America airline to near and far places and they have all given something to eat but this one NOTHING, not even water, you had to pay for it. This airline was the worst, first they wanted to charge me for my suitcase that I was bringing in which 50 pounds were free. Another reason was because I asked an airy one if it was possible for me to change to another seat since there were manyyyy empties seats in whixh she said/meant no; but the worst thing is that i still have one more flight with this airline. Im sorry if i am been selfish but this is how i feel.

This flight was less full so we could spread out more, but it still was not overly comfortable. My boyfriend forgot his phone on our last flight, but the crew was very helpful and got it back for him, which we appreciated very much.

It’s just not a comfortable plane.

The movies and entertainment offered in the screen were alright.

We were delayed over an hour because flight got in late from Halifax, I get it, stuff happens. Then once boarded we sat there for another 45 minutes. The pilot comes on over the speaker and explains we aren't leaving because the crew didn't have the proper paper work in the cabin...

Everything was good

One Stu artist who was a older women she was very grumpy, there was little to no turbulence the whole flight and if you got up to go to the washroom and we’re waiting and seatbelt light came on she would make u sit down immediately even if it wasn’t that rough, she made a girl wait for the washroom for 45. Minutes was kinda pathetic, when she was on her shift break not one person had a issue with any of the other flight attendants only her

I think the air quality on the flight from Toronto to Seoul was bad. I felt really neaseous for most of that flight and thought I would be sick on the landing. the illness went away completely once I landed and I didn’t experience it on the Asiana flight from Seoul to Phuket

The extra $50 seats were roomy.

Flight was delayed and no one knew why!... Plane had been sitting ready at the airport for hours. Novice flight attendants, they each picked on different things others missed just before them. No consistency, seats left reclined during takeoff and landing for example. One way there was drink service once even though it was a smooth flight and the return had drink service twice even though it was bumpier! Entertainment does NOT work on androids, it is NOT the AirCanada app they tell you to download prior to the flight, it's an AirCanadaRouge.pk file that needs to be downloaded in flight! Which means we're stuck paying for the iPad and of course only with cc because there's no wifi for debit cards.... AC needs to stop this insanely mediocre and yet expensive monopoly.

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.

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.
