Just booked an Air Canada Economy Flex (1st checked bag free, no charge to pick your seat)--one way from Washington Dulles (IAD) to Quebec for $323 including taxes. Was about 50 dollars cheaper two weeks ago; argh! should have booked then!
FYI: When choosing flight from the US, don't forget that if you have a connection in Canada before getting to Quebec, you have to clear customs on your first arrival in Canada, not when you get to Quebec. So leave enough time between your connections; the custom/immigration lines in some airports can be long and/or your next gate might be in another terminal. Or your first flight could arrive late. For example, we are connecting in Montreal and will have to go through customs/immigration there before going to our gate for the flight to Quebec. You usually DON"T have to pick up your checked bag(s); they will just be loaded onto your next flight.
