Everything was seamless and i have no complaints. My return flight was cancelled amd i was automatically put on a different flight, and instead of waiting more than 2 hours from boston to get to canada, i was put on an earlier flight for which i am thankful for. However we couldnt take off as delta was clogging up the way to the runaway so ended up waitimg an hour to taje off which was ridiculous. Hope delta hires more ground crew so that others arent inconvenienced in the future.

Our flight from Toronto to Houston was cancelled. The staff at the arrival counter was very slow and rude. We wanted to leave by the United flight which was leaving in an hour or so but the supervisor was not willing to do anything. We ordered Asian vegetarian food and it was horrible. Never again Air Canada.

When I bought the ticket I thought it was air Canada but it was air Canada rouge so no food no entertainment tried to download air Canada app but took about an hour to get 10 percent done so flew with no entertainment no drinks no food nothing. Boarding was a pain had a three year old also had to pay extra 50 dollars for my baggage. Typical air Canada nonsense. Would not use them again.

The layover was too short we missed our connecting flight. How did Kayak even allow us to book such an itinerary. Staff with the airline was also rude! Never will I book with site ever again!Rude

Not at all

I made the reservation without knowing that Americans airlines has a boarding number 9 where you are NOT allowed any carry on. Awful lesson. You are given the worst seat and you cannot store any thing in the overhead compartment. Or there make you pay $60..

Despite a departure delay due to necessity to off load some passengers due to nonfunctional seats we arrived 20 minutes early.

The seats are too narrow, which I can tolerate for about an hour.

The employee who checked me in was very helpful - found my frequent flyer number for another airline and give me a free checked bag.

The information that was given was awful. Why would AA send a broken plane to ABW?

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.
