The flight actually left.

Poor communication. Flight originally at 11:35, then 12:05, then 12:15... At 11:55, they said they would start boarding in 20 min. How can you do that and still take off at 12:15? Answer: you can't. Just be honest and keep us informed. Bonus: United sent me an email saying that connection had already left (it hadn't - thanks United! - awesome service as always!)

Very friendly cabin crew made this trip pleasant and entertaining.

Despite plenty of empty seats, the ground personnel would not consider changing our seat assignment at the gate to allow us to sit together.

I found the reason for being late to be questionable They said heavy snow but as i flew in i looked out the window and saw all roads nicely cleared That does not happen in 3 hours

They did not get my liggage to the connecting flight And here i am in Ukraine with no winter clothes at 7 below 3 days later

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.

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

Boarding was not done by groups, I end up storing my bag in the bin by the end of the plane while my seat was at the beginning and this was delaying my exit upon arrival. Not good experience having connected flight.

Crew was courteous and polite! Entertainment system had some great movies at no additional cost.

Poor communication between delta, KLM and Air France meant that I couldn’t check in online and get a digital boarding pass. Furthermore I couldn’t use the check-in kiosks because my name was listed as Reidmr instead of Reid, which meant that my boarding pass did not match my passport. Overall this caused unnecessary delays that were compounded by the fact that I couldn’t use my TSA precheck. My main problem on the plane was that I had to struggle to get water served to me. It’s always so dry on planes and I would have liked to be able to get more than one tiny glass of water at a time. Also, would have loved a window at my window seat. Plus no WIFI!?

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.

Not so good meals. For a 9 long-haul flight only one meal provided, other was a cheap candy bar. Other carriers do offer breakfast. Traveled with child and did not allow priority boarding at LHR. Limited leg room, I assume this already a trend well known by travelers.

Very rapid flight. Landed far before scheduled arrival(at least 25 minutes). Checked baggage was delivered before schedule arrival time. Crew was pleasant/helpful.

Flight was changed from what was originally scheduled and purchased. I was informed of the change after the purchase before traveling. Thus I had 4 1/2 hours between flights.

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.
