We were happy with the service and cost of checking a bag

Plane left an hour late, I missed my connection and my bow case was never even loaded on the plane in VA. I deal with this type of nonsense everytime I fly air canada.

Very nice staff members are very nice and friendly helpful

The internet connection was perfect, and the updated entertainment systems that allow me to connect my Bluetooth earbuds was excellent

It was good to receive a card for my birthday

It would have been better if it wasn’t cancelled

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

No TV's. Seats are super uncomfortable. Crew was great!

Service Director cut all cabin lights and window screens defaulted to dark, but it was an afternoon flight going west. I spent hours trying to see what was reading as reading lights weren't working either. What the hell.

The food could have been better. The flight attendant was the friendliest and most helpful I have ever had.
