This was like flying in the 90's. The seats were super small and uncomfortable my TV didn't work and they wouldn't let me use my phone (even on fly mode) and the Beijing international airport didn't have WiFi.

Boarding process was really quick. In half an hour they boarded a complete flight.

There was a very rude person sitting behind me. He kept hitting my seat every time I reclined it. I brought up to the flight attendant but she had no intention of getting involved or helping out.

I had to change my return ticket early because of an emergency and Air Canada charged me $481.00 whenI only paid $371.00 fora round trip. How is that possible?

One of the crewmembers (regrettably, I did not catch his name) was incredibly kind when I moved seats to accommodate a couple that wanted to sit together. He really made this flight great.

Seats were comfortable but the row I moved to did not allow me to recline.

The long wait on the aircraft after all passengers and crew were on board waiting for the oxygen tank to arrive.

Crew and flight were professional and courteous.

Passengers from Beijing were rude, and consistently snorting and spitting throughout the entire flight. Not just one person but everyone around us. Very disgusting and nauseating listening to that for 6+hours. I had earbuds in the entire flight and could still hear the spitting...

they should really do something about tight connections. If your first airline is only barely late, it becomes a frantic haste from hell to get thru security again and to your next airline. Security needs to inspect every element of your carryon in spite of the fact you were already screened on your previous flight. They will dump out your entire bag to inspect all contents. Extremely easy to lose important things. They confiscate all spare batteries if they only appear to be high power range regardless of what the actual voltage is.

Comfort and service on the plane. Lounge in Beijing was wonderful.

What you have to go through in Beijing to transit from one international flight to another. Very disorganized. I will never change planes again in Beijing after this trip. Perhaps it will be better on the way back. Business class travelers should have a special lane.

AC 018 takes the shortest route from Shanghai to Montreal. The check in and boarding were like a breeze. Cabin was clean, staff were amiable and hard working. The variety of drinks were plenty, the food matched the standard of cost efficiency flight ticket so how could you complain it? On board TV/Movie has new coming features such as HBO's Game of The Thorne, season 7. It was a comfortable and pleasant journey with the team of AC 018. Merci beaucoup!

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.
