Flight got delayed But satisfied with the pricing of tickets

Flight got delayed But satisfied with the pricing of tickets

I bought a ticket from Kayak. When I got to the airport, the was no ticket. I had to pay 5X to get to my destination. No response received from Kayak. I will NEVER use them again.

everything was fine. but paying for 1 piece of check-in luggage and denying passengers to board with carry-on luggage which by air line's standards does not fit is not acceptable. when one travels for a longer time one needs to have some essentials

Pearson Airport could not properly handle all the passengers who they needed to process in order to properly get them on board. As a result, I missed the departure of my flight from Toronto. The only saving grace is that Air Canada found a flight that only delayed me by one hour. However, this was no thanks to Pearson Airport!

The crew were fabulous. The flight was bumpy and I always like the captain to tell me what that is about or my imagination gets carries away.

I had a good experience. I liked being informed about the status of my luggage

The staff could have been friendlier. And Having the flight on time would have been much more convenient.

My wife and I especially liked the fact that the Toronto agent went beyond expectation to allow my wife and I to sit together. There was no option for us when we booked our seats. Very thankful!

I missed that flight because Air Canada did not send my luggage which caused delays at Customs

Flight was two hours delayed. Overall, I made it safely, so I am happy!
