We booked our flights with Celebrity for our Alaska cruise out of Vancouver. We are in Ontario and are flying West Jet to Vancouver and Air Canada back to Toronto. West Jet the bags are included and Air Canada there is a charge for the bags in U.S. dollars. The reason for the price in U.S. dollars is charged is because the flights are being done through a third party (Celebrity) that is based in the U.S., therefore the price for the bags is charged in U.S. dollars. The same goes for booking your seats in advance. We were charged in U.S. dollars for the seats. You can save the cost on the seats all together if you don't book your seats until you do your check-in for your flight. They will show you what seats are available for you. If you don't care where you are sitting or you don't mind not sitting with your partner, then wait and choose your seats when you check-in for your flight. Check-in for the flight is usually 24 - 48 hours before your flight is scheduled for take off. Hope this helps.
