Welcome to FT!

If you're interested specifically in Air Canada's Aeroplan, check the Air Canada forum on this site. That's where AC experts hang out, where questions about that airline are best asked, and where this one may have already been answered. If a search there finds that it hasn't been, you could click the Alert a Moderator button (black exclamation point in a red triangle under your name in the first post) to ask that this thread be moved over there.

If you're interested in another airline, any airline large enough to serve those routes has a forum here as well. Same recommendations: search; if not found, ask a mod to move this.

If you're interested in cross-airline comparisons, for which this would be the appropriate forum, please rephrase your question to explain it more fully.
