Better to not serve food if those are the options

It was a good experience flying Air Canada for the first time

They did not let us board because one member needed a transit visa, which was not evident at the time of ticket purchase.

I was charge a baggage checking fee $68!! I volunteered to check my duffle bag which usually goes under my seat!

Boarding - 3 of 4 flights were delayed and the gate staff did an ok job of managing the lines for boarding. Lots of standing around in line - more than typical. Crew - accommodating. If you are looking for warmth, you will not experience it with AC. But I appreciate their hard work and relative efficiency on 8+ hour flights. Comfort - My first 2 flights were cancelled the morning I was due to depart. AC rescheduled me on 2 new flights that created only minimal disruption and change to my itinerary (a longer layover, several hours difference in arrival time) and provided a 15 dollar food voucher for the layover restaurant which was the equivalent of a measly sandwich. My seats were changed which is a huge issue for my physical size as I require additional legroom for medical reasons, and I was put in a very uncomfortable seat without the option for seat selection. The bathrooms were incredibly dirty and foul smelling to the point of being nauseating and I was next to it during my longest of 4 flights. Entertainment - I always travel with downloaded entertainment on my own devices and a power bank, and am glad I did! The entertainment was completely non functioning for my 8+ hour flight home. We were provided a 15% or 50 dollar voucher on a future flight by way of compensation. Food - always just poor to mid. I also travel with my own food when possible as in flight meals and snacks taste strongly of packaging. Overall, this was a poor to mid experience, and I am resigned to the fact that airlines are never going to improve.

I did not like anything because the flight was cancelled yesterday and I did not get to arrive on time in Toronto as I was rebooked with another airline. This caused me to be really stressed out as I am an individual with back injury and to be forced to stay longer in an airport to accommodate a change of airline and the transfers associated with it Due to this I am probably not going to book through your website to eliminate this potentially chaos in the future

shittiest airline in the hemisphere. To improve - start thinking you're flying people, not cattle

Easy boarding, inflight refreshments came on time and comfortable seat

Flight attendants were ok. But it was a full flight.

It was good that our flight left early. It was a nice smooth flight and landing.
