Blondbomber,
very sorry, for some reason I thought you were female. In fact one time someone called you "he" and I thought, boy that person is biased... oops. lol. Anyway, again sorry.
I would certainly hope your company could spring for the hotel, given the miles you are willing to go in order to save them money!

lol, just hope your boss and/or travel department isn't also on this board... or they will know your plans!
You definately have a big advantage on upgrades, if using a oneway upgrade certificate, of course if you have distance based certs you are in trouble.
and you know, some of those OneWorld Round the world fares aren't much more than that trip to london... and might be cheaper than those segment fares within canada... stop by bangkok on day 7 and have a drink with tummyg?
