Good value, minor delay due to waiting for inbound plane but they gave accurate information about wait time. Able to switch to a seat by my husband thanks to a kind flight attendant

Good value, minor delay due to waiting for inbound plane but they gave accurate information about wait time. Able to switch to a seat by my husband thanks to a kind flight attendant

7 hour layover was a drag. Free internet on the long leg was great.

Staff were courteous and helpful. The only negative was the flight delays (which are usually unavoidable) and the high baggage price.

From vancouver go calgary nd vice vetsa fligjt was delayed

Absolutely terrible, from the customer service to boarding the plane. On the phone, there was some mishaps with getting in my correct date and they did not help me retrieve a refund or any assistance. I’m gonna be reporting to all my followers and family around the region of Los Angeles to New York.

Arrival at Comox from, London,ON 6 hours later... No bueano

Generally good. However. The flight left 30 mins behind schedule with no reason given.

Flight delayed, missed my pick-up had to Uber, plus missed dinner and medication, so sad!

Nothing to like because my inbound flight was cancelled without notification by West Jet or third party, JustFly. I couldn’t take the inbound flight due to cancellation; therefore could not take the outbound flight back.

Not the greatest experience everything was pretty mediocre. My seat was by the washroom in the aisle and was not located well as everyone past each other people were right in my seat and space.

Flying in the Dreamliner is always comfortable. Though the food options for Air Canada aren't great.

Flight got delayed for no reason. And Air Canada was doing 3 boardings via the same gate. It was chaotic!

I n the Toronto airport I had trouble finding my zone. It was 47. I went from Zone 1 to the end of the line.didn't find it. Then saw my zone somewhat by accident over by where you first come in. Signs could be more helpful or more personnel directing people like me.

Wonderful airline. All staff were pleasant and helpful. What is sad is that it wasn’t grand gestures just everyday pleasantness and friendliness that are missing from the other airlines I have flown recently.

Friendly efficient crew, but plane had no way to charge phone. That is a near necessity with today’s travel where we carry out travel documents on our phones.

Orderly boarding. The flight to Montreal was difficult to get to on time, but had help from staffer.

Orlando to Canada, despite being close and an international flight, the plane was not at all comfortable. It felt like the chair was being pushed forward, in addition to not having a TV and having to choose from a tiny glass of drink, for example, water or soda. I couldn't have both. When I asked the flight attendant for an extra glass of water, she looked at me with an ugly face. This is ridiculous. They don't want to give water to passengers. I will never fly with this airline again in my life.

The checking of my carry-on was not the greatest idea. It was selected for a security check in Toronto and didn't make it to my connecting flight. Fortunately Air Canada delivers late luggage to Whistler so I got it at 2 A M.

The seating and lack of leg room. I paid extra for more leg room. The space for under seat storage was a joke.

Well managed flight comfortable. Wish they had back of seat screens
