LATE AGAIN. Seems like each time I use Air Canada there are delays ... extra 2 hours this time, making for a 22-hr day for me!!! The gate people did not seem to know what they were doing with loading people, unloading, checking carry-ons, letting some go ... very unorganized from Toronto to Detroit! Would have been faster to drive

LATE AGAIN. Seems like each time I use Air Canada there are delays ... extra 2 hours this time, making for a 22-hr day for me!!! The gate people did not seem to know what they were doing with loading people, unloading, checking carry-ons, letting some go ... very unorganized from Toronto to Detroit! Would have been faster to drive

The staff were on the last leg. But they were still very accommodating and polite. They were all very helpful with getting the bags up and getting people to their seats.

We were delayed by rain while we were on the tarmac. The crew came around and offered everyone water while we waiting 45 min in the plane.

Flight from Lisbon to Toronto was smooth, and we arrived early! Flight from Toronto to Denver was delayed about 40 minutes. We didn’t hear about the delay until after we had boarded the plane. The delay could have been handled better.

The seats were comfortable. However, be prepared to provide your own food (snacks) and drink. We had a 3.5 hr flight, one service was provided, a 4 ounce beverage. Saw flight crew for beverage service and trash pick up. Unless you purchase a meal or snack, nothing is provided. I am fine with bringing my own, but was accustomed to snack and beverage provided regardless of the duration of the flight. And note… typically a full size drink option on longer flights.

Air Canada cancelled my prepaid/prebooked seat selection and changed my seats without any options.

They canceled the flight on us very close to the flight date .

The first flight Seattle to Toronto was very poor. My seat was changed. The aircraft was changed. They were having issues with the meals. My second flight from Toronto to Quebec was fine. Short flight still no entertainment. My third flight Quebec to Montreal was very short seats are very uncomfortable, too old and way worn out almost like sitting on a bench. My last flight Montreal to Seattle was fine. Finally, they had some entertainment. Proper food was offered as advertised flight staff was accommodating and friendly, but once again, the aircraft seats are hard like benches.

It took 66 hours to get from Seattle to Tel Aviv. As a minor, I was left for more than 12 hours in Toronto and Frankfurt without hotel and food vouchers. It took 5 layovers. It was insane and not okay

It was delayed but got us to YYZ. I had great copassengers.
