How Often Will America West Have First Class Upgrades Available?

I've never had a problem buying an upgrade on HP.

Whether or not this changes with the US merger is another story.

America West has low-priced options to upgrade a ticket to first
class, but only for 30 hours before a flight. I assume that
for a large number of flights those first class seats are all
taken and no upgrades are available. What percent of the time
will first class upgrade seats be available within 30 hours of
the flight?

A related question: on what kinds of flights are the first class
seats least likely to be taken? I assume on short flights first
class is not filled, and on longer flights first class fills
pretty fast, but maybe I'm wrong?
