Interesting thread!
I'm probably going to have the most unusual job here - I'm an international cat show judge.
I travel about 24 weekends a year - used to be US exclusively when I lived on the east coast, but now that I fly out of Seattle, that has changed.
Internationally, flights depend on the location - I'm off to Australia in July on Quantas - and will be going to Italy in Sept.
Flights to Canada now usually involve driving to BC and flying either AC or West Jet
