I turned down a faster and cheaper flight because it was going to charge me for checked bags. It was only when I got to the airport that I was notified of the checked bag fee (which was hefty). This was never listed when I purchased these tickets, and I would not have bought from you if I had know this was your plan. I am expecting a refund for what I paid for the two checked bags round trip. If not, I will make it my life's hobby to let everyone know about your companies business practices.

The crew & service on our Denver to Munich flight were incredible. Courteous, professional & fun. A crew like this makes flying a pleasure.

The seats in economy on the A-350 were a horror show. Couldn't have made them more uncomfortable if they tried. It seems with each new model Airbus puts out the seats regress to more medieval technology.

We were able to upgrade to a business class seat (row 1) just 2 days before the flight since we had put in a bid a month before to do so if it was accepted. Honestly, the seat DID NOT EVEN RECLINE, NOR DID IT FEEL VERY SPACIOUS! I felt very taken advantage of to only have access to that part of the plane giving us more leg room for $200 upgrade for each seat. When does a Business Class seat NOT recline??? At least my flight attendant was kind enough suggesting that I let the airline know about my unhappy experience.

For relatively new aircraft, the comfort of AC’s 787-8 economy seats is not up to par. A frame cross member presses the back of the buttocks, there is minimal lower back support, and no protection from the hands and knees of passengers behind.

It appears that Air Canada is doing the correct thing for passengers who have reserved their seats in advance....after many years of not applying their written policy of making them board after business class/disabled passengers/passengers with young children, they have created Zone 2 boarding which permits passengers with reserved seating to board immediately after them, therefore guaranteeing them overhead bin space. As we all know, a lot of passengers board with much more than one carry-on, which is a plague when boarding.

Sat near the back. Air Canada has installed new seating on this route that is absurdly close together, with truly the most inhospitable seat shape and unforgiving cushions. For a 5 hour flight, it was awful. My back hurts.

Pilot was great— we don’t thank them enough for a smooth and safe arrival. Plane was great. Ammenities were given (such as ear plugs etc)

Crew members are a bit bland and lack customer service, but I noticed that as a whole in Australia (slow service/not really interactive or communicative & very quick to make comments and leave) not sure if they just hate Americans based on the media or what. One crew member cut in line at the restroom when there was 3 of us waiting to go. Another told me my husband couldn’t receive his meal because he was napping and then he quickly walked away— Yet i received mine on the flight coming to Australia when my husband asked for me? Sanitation between flights should be more strict-my headphones were opened which lead me to believe my pillow wasn’t changed either, since one had a case and one didn’t.

I could of flown with Air transat and get better than I got with Air Canada. I feel it was rip off. Quality - price not there . Please give your crew a better uniform.

We paid $100 per person to choose our seats in advance and then when we boarded we had been bumped to a different location and my wife and I were sitting across the aisle from each other, unable to share a tablet to watch movies. The cabin crew was not helpful at all so we traded seats with another passenger who had also been bumped from his preferred seat. The entertainment system didn't work for an 11 hour flight.. are you kidding. We pressed the call button to see if it was just our inability to sign in but no crew member came. After 15 minutes the call light went off so we pushed it again, but the light was still on an hour later. We asked about it during the meal service and were very rudely dismissed. Long after meal service was finished we asked one more time to see if anything had changed and the crew member brought us a tablet to use that was loaded with movies. I'm not sure why they didn't do that earlier. Then 50 minutes before landing they literally pulled it out of our hands to store it away.

Kind crew helping a frightened passenger

Terrible, frightening turbulence and illogical birding. Why not bore back of plane to front of plane?

Food was good. Intertainment options good.

My seat did not recline so I had trouble trying to sleep thru the night flight. Seats too cramped even after updgrading.

Like the infotainment unit on headrests. Decent movie selection.

Seats are cramped when person in front leans seat back.

Our plane was broken. Initially they said an hour late and then the time before our flight increased. Because our flight was delayed, I missed I missed an important meeting.

Overcrowded, no leg room and staff unwilling to help move two travelers near each other. Did not appreciate the rough demeanor and having to flag down attendants for water when they skipped over our aisle. Would avoid this airline in the future if possible.

I turned down a faster and cheaper flight because it was going to charge me for checked bags. It was only when I got to the airport that I was notified of the checked bag fee (which was hefty). This was never listed when I purchased these tickets, and I would not have bought from you if I had know this was your plan. I am expecting a refund for what I paid for the two checked bags round trip. If not, I will make it my life's hobby to let everyone know about your companies business practices.

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.
