By modern air travel standards, our 15-hour flight to Delhi was very nice. Quiet-ish, straightforward, good service, okay seats, etc. All good.

By modern air travel standards, our 15-hour flight to Delhi was very nice. Quiet-ish, straightforward, good service, okay seats, etc. All good.

Again, it was delayed and then our connecting aircraft was very cold.

It was very cold in the beginning; then I asked stewardess to do something about that, and she did something, so for the rest of the flight the temperature was closer to normal. It is typical: by some reason the pilots or whoever is in charge make the cod in the cabin unbearable. The seat is better than on WestJet or Flair, but is is very tight. No leg room.

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!
