Mediocre 3.0

Pros: On our longer flight, we were thrilled- nice crew, delicious food, spacious, great pilot, and enjoyable entertainment experience. However, on our shorter flight from Brussels to telaviv, not only was the crew completely inattentive, but they were intentive to some very disturbing things including children who were pulling the hair of other customers and jumping up-and-down in the aisles of the airplane. There was no available entertainment whatsoever. In addition the food was extremely expensive and not particularly tasty. The plane was uncomfortable and smelled atrocious. These 2 vastly different experiences almost made me feel like I was taking 2 different airlines. Please keep consistency.

Cons: I didn't like the inconsistency of the 2 different planes that I was on. If you are going to have entertainment you should have some form of it on all of your airplanes. The idea that food that you need to buy is so expensive is absurd. I was really blown away by how badly the plane smelled. It was almost as if I was in a bathroom. And on top of that I really felt very unsafe with children jumping up-and-down kicking people pulling their hair etc. While it isn't the job of the flight attendants to be parents, they certainly need to be aware of safety concerns for the rest of the passengers.

Okay 5.6

Pros: We finally got to our destination

Cons: Weather delayed the flight by around 4 hours. Crew at the airport were clearly stressed and took it out on stressed passengers. You had to ask for everything rather than the crew proactively doing things to make people comfortable (regular updates, food vouchers, going around making sure people are comfortable). Captain on plane was good. Crew on plane was ok, more socializaing with each other rather than being proactively helpful.

Good 6.4

Pros: Short of the entertainment system incident, the service was pleasant. It was nice to NOT be on a full flight and have both seats to myself.

Cons: Entertainment system was not working, and crew was fairly nonchalant about it. In the past they at least apologized and on the better end gave out drink vouchers. Not this time.

Cons: Air Canada continues to underwhelm me. We left the gate 35 minutes late despite having everyone on board. Then off to de-ice where we sat with a truck outside for ten minutes they did work.

Pros: I like that the pilot to managed to take off in the snowy conditions and arrived our destination LA our time. The crew was amicable. That was it really.

Cons: I felt the plane was not very comfortable for a 5 1/2hr flight. I will not fly this plane never on transatlantic it just not cozy like big airbus or b777. Air Canada should invest in big planes if it want to cash out on the passengers connecting their pacific flights.

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.
