Stood at check in for over 30 mins with no staff in sight. Boarding was a disaster. Staff was not prepared nor organized and the crowds were unbearable. Upgraded seats were laughable and not worth an extra $60. Food was mediocre. Entertainment would have been good but GE touchscreens are so old, they were difficult to work.

Flight to our destination: sat in exit row for extra cost. I was freezing cold and was told no extra blankets. Also staff were rude and unhelpful telling us to remove all things from the floor for take off and landing ( which i accept is the policy) but since we had nowhere to put them except on our laps (she’s, books, sweaters pocket book) as there is no seat in front for an exit row to put under. The staff member kept saying “up, up” motioning with her hand, but made no offer to assist us in finding overhead space. Upon our return flight, our pre booked exit row seats were switched on us right before boarding in a rude and matter of fact wayand my husband and I were separated one on either side of the aircraft. When we queried this, we were told it would be up to us to switch with the person sitting next to us. Overall very disappointing. I would not fly Iberia again.

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

Improper handling of situation. There was flight scheduled later, but CS agent kept jerking us around. By the time I reached the United counter, the next flight was full. My total flight time was 36 hours. I still can’t believe that the pilot was missing. Worse yet, the agent at the gate could have made things much easier instead of telling everyone that a pilot was on his way to the airport.

There is nothing to like about Air Canada anymore.. unless you happen to like the abuse and indifferent service. Employees seem disengaged.

AC used to be mindful or customers with connections. This is the reason I booked all segments with air canada. Found out the hard way it is no longer the case. Lesson learned. Missed connection and ended up on stand by for the next flight ( no more protected seats folks). Was not even refunded the money paid for seat assignment on the missed connection.

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,
