Welcome to Flyertalk,
shore9.
Since your profile says you're from Canada, your flight example departs YVR, and you refer to "SE" I'm guessing your question is specific to Air Canada.
Your question and thoughts will probably find the most appropriate audience in the
Air Canada forum, so I'll go ahead and move this post there for you.
(Of course, if I've misread your intentions I apologize.)
Best,
Gary
