question:
In the AAdvantage program, there are 3 statuses, Gold, Platinum and Platinum Executive. The Platinum has a "72-hour upgrade window". The Executive has a 100-hour window. I assume this refers to when you can sign up for an upgrade and essentially get in line for an unsold first class seat.

Do all these seats invariably go to Executive members, or do Platinum members have a chance at them? In other words, what I am thinking is that if there are dozens of Platinum members on a flight in economy and they all sign up for an upgrade, then there might a long list of Executive members in the line for just a handful of first class seats. But if there are not so many Executive members, then maybe Platinum members would have a shot at those seats.

What is the common experience?

answer:
Probability of first-class upgrade with only Platinum status?
