The Turkish was good . I had a problem with air Transat terrible experience for me

I did not like I have been charged for my carry on

Onward flight was okay. return from Lisbon was poor as we missed our flight due to a long line at the passport control. Air Transat made no effort to accommodate us even though we were at the passport control 40 minutes prior to the departure.

Very good. A lot better experience then I expected for an economy flight.

It was very good but no tv but the experience was great

Thank you for making my first experience very enjoyable. You made it all very pleasant

Great flight great seats will absolutely fly with you again

Porter airlines was good. I didn't have the best experience when booking through airfare assist however, as I got no final confirmation from them that the flight was booked until I called them. Even then, the confirmation code they gave me was incorrect and couldn't be used for check in. On a positive note airfare assist was actually picked up the phone relatively quickly when calling

The flight crew were very good, polite, and professional. Unfortunately, the rest of the experience left much to be desired. The food was extremely bland—almost tasteless. We chose the non vegetarian .The lasagna was just plain pasta with a tiny garnish and no seasoning. It felt like eating starch only, The bigger issue was with luggage and space. We boarded with three tickets, and while the seats in front of us were nearly empty, all the overhead compartments had already been filled by passengers boarding to the back. This left us and many others with no overhead storage for our carry-ons. Our bags couldn’t fit well under the seats either, which meant we lost the little legroom we had. The result was a horrible, cramped experience—sore knees, no space to stretch, and no way to rest or sleep comfortably. According to the crew this was a rather normal thing. It is obviously normal that people board with handbag and carry on but they should be only allowed to use their overhead compartment and under their seat not the way it is managed that all the spaces in the front of the plane being occupied by the people sitting way back in the plane.

The on-board entertainment system was horrible - we gave up watching because it just kept glitching.

Had to cancel the flight because there was a 14 hour layover before the flight. Unacceptable.

We had originally booked our flight from Punta Cana to London Ontario but our flight from Toronto to London was rescheduled and we would of had a 14 hour layover in Toronto before caughting our flight to London which is unacceptable. So we canceled our flight to London with no compensation and booked Robert Q Airbus from Toronto to London. We are not planning on using Air Canada for any more travel trips. In the last year and a half, Air Canada has rescheduled my flight from Toronto to London 3 times and forced me to cancel the flight and take Robert Q to London to avoid a long layover in Toronto. I received no compensation for the flight which is unacceptable. I'm very disappointed in the way Air Canada always rescheduled my flight from Toronto to London.

I wish Air Canada would provide a meal on the 5 hrs or more time flight to the passengers.

Terrible… Luggage’s missing for 5-days. Not expedited despite notifying them that insulin and ozempic were in bags and required refrigeration. I’m extremely disappointed. Meds were useless upon delivery as ice pack had dissolved and meds were warm and not useable because their efficacy and potency are now questionable . I’m so disappointed and expecting a full refund for the checked in bags.

Was delayed at every point/ connection. Luggages missing for 5days. Had no medications for diabetes and high B/p. when bags where finally delivered on the 30th, the insulin and ozempic were no longer patent, as the ice pack had since dissolved and the authenticity of the med is now questionable, since they must be refrigerated. Please have them refund my bag fees. I should sue them for all the inconveniences caused to me.

The plane was delayed substantially due to a mechanical problem, that being said, the airline was very fair with providing a meal coupon for us. I would rather arrive late on a mechanically sound plane than the alternative. The food served in the plane was just awful, however and I recommend a new catering company.

Very bed experience never want to travel air canada anymore

I liked all of it, and excited to do it again~* Thank you, and Much LoVe and Respect, CHRiS aka KRYSTOE 👣🎵 http://www.chrisrousemusic.bandcamp.com Google = chrisrousemusic and/or KRYSTOE

I travelled in Business class for the first time and wish I could do that again.
