people in Vancouver forum advised to ask here about carrying extra luggage in flights from Vancouver to Whitehorse. I have booked a flight with WestJet and need an extra luggage piece; in their website there is a price (quite reasonable) for it but no information about procedure how to check-in (with other airlines there is option for prior-to-flight booking). Do we just bring our luggage to check-in and pay for an extra piece there? And what are chances that we don't get it in flight because airplane baggage capacity is reached?
Thanks in advance!
