First off, if one is waitlisted for such upgrades, what is the order on the waitlist? Status, date booked, class of service, etc. If, e.g., V-fare + $$$ is more than H-fare, does this make a difference?

Ongoing complaints. 1) When you try to book, you are not told if BF upgrades are available until you ticket (though I was told if we paid full-fare coach, we could upgrade with miles; no thanks, waaay too costly). 2) At least they are finally telling us this --- if you have a domestic leg connecting to the intern'l leg, and if you are not upgraded to BF in advance, on the day of travel, if you accept the domestic upgrade, your full miles (one-way) will be deducted (and it makes no difference if you think you had a status upgrade).

None of the above is new, but its been awhile since I've tried to use CO miles in this manner, and am still upset about all this nonsense we have to go through.
