The routing I used to come up with that approx. number is YYZ-ORD-MSY-ORD-LHR-DUS-LHR-HKG-SYD-MEL-SYD-LAX-ORD. On a paid F fare.
I do see your point on keeping the top tier exclusive and have no problem with that. Based on what I have found out and what I read on these posts it won't happen, but for the price of a fax I'm willing to try!
I'm curious what you feel are the benefits of Exec. Plat. that are not in black and white, if any?
