Not enough electronic outlets for charging in the Air Canada waiting to board area but the Most important thing….the plane was booked to only 40% capacity and my row of 2 other seats were empty. My row happened to be one of the few rows that did NOT have raising arm rests. The flight attendant made effort to seat me in a different row. I needed wheelchair assistance due to a cyst on my knee and struggled to move from seat to seat to get to the row. Those 2 empty seats tormented me the entire 15+ hour flight as I had to be upright the entire flight and was not able to elevate my knee. Lots of other passengers were laying down due to the arm rest being able to retract. It is a shame that he couldn’t be gracious and find a row that I could move to.

Crew was pleasant and efficient. The speaker system for instructions was hard to understand

My experience was poor with customer Services. Please consider flexibility with cancellation due to emergency health condition. Thank you.

Terrible. Flight was delayed for hours and we ended up arriving at our home at 4am after 20+ hours flying.

Disappointed my flight was delayed to TO as i had a connection to make. Ran through the airport I made my flight but I initially had 1.5 hours to connect. Unnecessary stress!

From my experience, I see there is room for a greater mixture of cultures, for example, a mix of the nationality of cabin crews, food, music, food, etc.

Flight was cancelled around 45 -1hr minutes before scheduled take off time due to mechanical issues we hadn’t even boarded yet. Had to reroute to Orlando so someone had to drive 2 1/2 to come and get me… the alternative was go through Toronto and get a later flight which didn’t work for my schedule. The flight attendants barely gave anyone a smile…not the same as flying when a client/passenger was important. Very disappointed. By the way I have never ever made a complaint online about any company with feedback…even when I probably should have. The only good experience was the boarding desk associates who were very professional and got me on another flight with my checked bags…very nice team.

Actually as my experience with air Canada from Canada to Newark it was crazy for me because it was a lot of delays which for me it shouldn’t be like that, but I was able to coup with it so that was my experience I hope next time they will do good on that thanks.

Delayed delayed delayed cancelled and all we got was $60 food or beverage Embarrassing I'd say

It was fine. There were a couple of mechanical delays prior to takeoff but it was overall a quick and pleasant flight.
