I like the free air Canada wifi and being able to watch things on there. The basic snacks are good, just wish I could have both. If I’m being really picky, the flight attendant who filled my drink, filled it half with fizz and didn’t take the second to let it go down and add more, so I got maybe half a cup of pop.

I like the free air Canada wifi and being able to watch things on there. The basic snacks are good, just wish I could have both. If I’m being really picky, the flight attendant who filled my drink, filled it half with fizz and didn’t take the second to let it go down and add more, so I got maybe half a cup of pop.

Snacks were just placed and many people were hungry and unaware they were available. Ran out of water bottles. Attendants not available. Missed entire meal.

Very Bad experience with Swiss, they robbed me for additional baggage and misguided. The flight was delayed for 2hr 55 minutes, screens were not functional and food was also bad.

The free Wi-fi for Aeroplan members was a great touch. The time passed quickly. I found the seats seemed a little closer together than I remember. Not Air Canada's fault, but we were about 20 minutes late landing because the airport was too busy. We had to circle around for a while. The boarding and disembarking went very smoothly.

Too many delays. Seats too small. A budget airline. Will never fly Air Canada again.

On board wifi or other entertainment. Landlines option was good but ran late to Pearson

Extremely turbulent landing. Crew was friendly and plane comfortable. Airport and US pre clearance was understaffed

More space on a sold out fight and food trays were dirty

The airplane is way too tight, you can hardly enter into your row to sit.. more like kids seats than adults.

My original flight was cancelled -- but I have to mention the excellent service I was given by the agent working at check-in who found me an earlier flight -- and helped me navigate security, ensured my baggage kept up with the quick check-in and boarding process -- and just generally made the re-booking process a breeze. Thank you! On flight was fine, but we unfortunately meant no in-flight service -- no water, or coffee (it was an early morning flight...), but the crew was pleasant and accommodating throughout.
