1. Everything was satisfactory concerning the flight. 2. Can't think of what could be better right now.

The kid in the middle seat kicked me almost the whole flight, almost kicked my hot tea off my tray. The flight was delayed due to the first plane not being able to be de-iced in July! We had to get a new plane. Now I drive 3 hours back to Edmonton because direct flights from PVR were way to expensive

Excellent communication from the staff. We actually arrived early. Very friendly and professional staff.

The entertainment they offer could use some games, and maybe they could add some cookies to the snack menu. And the automated messages are a bit repetitive. But it was comfortable temperature wise and the seats were comfortable. The crew is very polite and helpful

I felt scammed. The priced advertised was different than what I paid. I paid the whole some online. I then got a call 20 minutes later saying I need to paid 70 more person. She said the price online is not the guaranteed price.

Some crew were unfriendly or in some cases just straight up rude.

Putting people that close to the bathroom, where you have to look into the bathroom as people are exiting and entering was not great and the smell was also not great. I know the airlines are desperate for more chairs, but that seat is a crime.

one staffer was frustrated (it happen); the flight was late and the pilot mentioned they'll make amend but the snacks were the same, other than that the aircraft was clean and everything went smooth, no complaints

ticket agent lady wás very helpful , she arranged wheel chair for my elderly mother

Entertainment kept turning itself off. Gave up on watching a movie.

Flight was delayed and rescheduled 3 times before being cancelled. Flight was also delayed on our flight in at Moncton airport on August 10th. Never flying with PAL again.

Connection was easy to find and quick. Plane was older but comfortable. The food contained beans again so a similar problem of being in a tin can in the sky after eating beans. Overall flight was uneventful which is great.

Just a two hour flight... boarding was smooth and easy going... flight was smooth... crew very helpful... snack of pretzels was awful, that needs changed...

It was good. The tray on the seat was not cleaned from the previous flight. The seats are tight but I had no one beside me. The crew was great.

It was 3 hours late and ruined my plans at destination. Also rough landing.

Very bad I put my stuff down to go through the machine and when it came out it my watch was gone. Then they have the nerve to say I have to file a report that's b.s.

The experience with Air Canada was nowhere near what I would expect considering the ticket price. I feel as though I was robbed and had horrible, the worst I've experienced across any industry, at every touch point throughout the flight. I will never fly Air Canada again and will do my best to discourage everyone I know from choosing this airline as the experience was so horrible I would not want anyone I care about to have to fly Air Cananda. Shame on you Air Canada - you set a new low standard.

I’m a creature of habit and I like to sleep while I’m in the air

I was not impressed by the ground crew in Toronto. The crew on board the plane was efficient and pleasant. The ground crew in Saint John was outstanding.

Left 2 hours late due to staff shortage. Did not arrive at my destinations until 1 AM and my wife was stuck waiiitng all that time and my pet in cargo was also cooped up for 2 hours longer than necessary. Sorry but this was not,good.
