We were treated well by the staff at the airport and on board aircraft. Delay was uncontrollable due to the weather. Had to wait for another gate as we were late landing in Fort Lauderdale.

We were treated well by the staff at the airport and on board aircraft. Delay was uncontrollable due to the weather. Had to wait for another gate as we were late landing in Fort Lauderdale.

I was supose to have a carrey on incluided for each passenger and they made me paid 75$ each at the gate.

Great crew and entertaining Captain. Seats were not what we had expected based on my booking but things worked out in the end. Of course, like all airlines these days not enough leg or elbow room.

The entertainment system was down; food by purchase only; several people did not receive their luggage. No one answers at the local office or online about the luggage.

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

Delayed for 15 min due to maintenance. We were asked to wait to board as a family, but took longer than if we were not asked anything.

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

Terrible…. Reported missing luggage’s with injectable meds that needed refrigeration. Yet, delivery could not be expedited. Luggage’s were delivered 5 days after arrival. The meds were useless as ice pack had melted. So disappointed!!!

Terrible, luggage’s with b/p and diabetes meds including insulin and ozempic. I’ve in them had dissolved and rendered useless

It was a very small plane and was ok. No food or entertainment so there should be an option for NA.

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

The crew from Toronto Santiago (and the other way) weren't nice people. They seemed angry. Other flights with Air Canada had much nicer crews. Bathrooms always had sticky floors. Yuck!

No entertainment system. Paid extra for wider seats but not worth the cost. Flight left a little late and arrived early.

We boarded and then deboarded the plane after being told it needed something done that couldn't be fixed. Sent notice about 3h flight delay, then they clawed it back and we were 1h delayed. Very poor communication.

Was notified on a timely manner of any changes, if any, of the flight schedules.
