Pros: The plane left on schedule.

Cons: I was asked to check in my carry on but I couldn’t do it bc I had lots of fragile items packed. I was told that overhead compartment was full which was not true as there was a lot of empty space left.

LHR
BWI
Okay 5.3

Pros: Did not realize I purchased a “no checked bag” fare - and the $60 each way charge really pissed me off, along with the &48 charge to guarantee a window seat again, each way. The site was misleading, and I resent being peneluzed for trying to be efficient. A two week work trip needs to include a checked bag.

Cons: For a new plane, seats are very cramped. If you drop an earpiece on the floor, you pull a muscle to retrieve it / or make. Everyone in your row stand up. Decent movies mean a box under the seat cuts into legroom. A cramped, miserable 7 hours for this 6’0 tall American. Staff was as helpful as they could be, but my knees still hurt.

Okay 5.6

Cons: I bought my ticket with Air Canadafrom Vancouver to Calgary then connected with Lufthansa from Calgary to London UK. Unknown to me I could not find the flight because it had been changed to an AC reference flight. With a very short time for the connection I did not know where to get my boarding pass as my flight with Lufthansa was nowhere referred to ! Not which gate to go . Why not put it in the ticket that Lufthansa and Air Canada work together and that both flights ref should show !! It would avoid a great deal of anxiety . Only offered 1 round if hot drinks over 9 hours ! Departure delayed by nearly 60 minutes

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

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.
