Most memorable would likely be my first business class flight heading for GVA in 1983 (I think--perhaps it is not the most memorable
). I had booked a full economy fare but they bumped me at the gate into "Connoisseur Class" which was really more akin to modern non lie-flat Business Class in those giant old overstuffed seats. Lots of free booze, including Newfoundland Screech. Had two seats in a private area all to myself. Had trouble waking up the next morning in GVA!
Other memorable trips are on Dash 8 Calgary to High Level when mainline carriers still flew there in a completely empty plane (except me) and flying in the jumpseat way up front with my sister in law doing flight attendant duty on the flight.
