None of the experience was pleasant

First flight was delayed causing us to miss the 2nd flight and we ended sleeping on a chair at the airport waiting for a morning flight. AMERICAN AIRLINES didn't even have the decency to put us in a hotel for the night due to their delay. Then they added a 2nd lay over which was delayed for hours also. Traveling was to visit my mother who had cancer and I was sick so this made the trip even more distasteful.

Flight was delayed multiple times. Flight was scheduled to take off at 1210 pm, delayed to 1510, delayed again to 1700 then delayed to 2110 and hen finally boarded at 2230 but the flight did not take off for an additional 2 hours making the total flight delay 12+ hours. My mom did not speak English and the staff at the boarding gate would not provide her a translator nor where they willing to talk to us over the phone to assist her. I understand that delays happen but the lack of assistance and multiple delays was alarming (with clear weather). Air Canada device over the phone was unprofessional as well when I called to discuss the lack of assistance we received.

Arriving and calling someone to help me with the wheelchair was good. The women were so friendly and helpful. But when you're "stuck" in a chair and I arrived early, it would be nice for someone to check to see if you had to go the washroom. And I had to flag someone down to get me to the aircraft. No one came by and offered. But overall fantastic experience. I would fly porter again.

Wish their was more food on the flight. Even though it was a short one.

That we eventually got a flight home.

Being stuck in Boston and Ottawa for 2 extra days and adding around $1200 on to our trip in hotels alone (I was travelling with 4 kids on a school trip and my wife). Additionally, we didn’t find out the flights were cancelled until we arrived at the airport. Apparently, they had been cancelled 2 hours before but there was no notification. Air Canada offered no help whatsoever and the guy at the “service” desk in Boston literally said there was nothing he could do to help. Not even find a new flight. Spent 90 minutes on the phone trying to re-book, plus re-booking hotel along the way.

The flight wasn’t full, so I sat in my own row,?which offered spare leg room (I’m 6’2”). Time to fix the leg room issue on Rouge flights — it’s 2018.

Crew seemed uninterested in general. On phones in back while people struggling to find luggage space. Coffee cups and plastic utensils, etc, stored in overhead bins so people at the back had to search for carry-on space elsewhere, again, without assistance from on board crew. Offered service only once and many were sleeping so didn’t get anything. The overall check-in process could be easier, as the app doesn’t always work as it should.

This was my first time flying Air Canada. Our flight was delayed by 4 hours because they had to deice the plane. Yes it was frustrating but I would much rather have a flight of upset passengers then risking our lives. The captains and the crew went out of their way to make sure that we were the most comfortable. They gave us food and drinks as we waited and were extremely patient. Upon arrival many passengers had missed their connecting flights, including myself. They put us on the next flight out and gave all passengers a hotel and meals for the night. I would definitely recommend Air Canada. The plane itself is also pretty spacious so don’t be afraid to fly economy.

Nothing really. They were great. I mean, definitely wished my flight wasn’t delayed. Although It wasn’t their fault that they needed to deice the plane, that’s something that should’ve been accounted for way before our flight was supposed to take off.

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.
