Thanks everyone for helping me as a "newbie" to the standby game. Here's how this played out for me today. I tried to get on the waitlist online at the 24 hour window yesterday. No luck, no standby options available at 24 hours. I checked periodically thru the evening. At midnight, all of the SEA-MSP flights "opened up" for standby, so I picked the flight I wanted. I was told adamently by a couple of Gold/Plat WP Elite agents that this flight was oversold by 10 seats, even though there were 10 seats open in FC at the 24 hour window and many seats still open in the "premium" section of coach. Thru my own fault, I wound up arriving with not much time to spare at Sea-Tac this morning. By time I got thru security, took the tram over to the S concourse and made it to the gate, the GA's were just starting the pre-board for the earlier flight I wanted to get on. I waited for my turn in line with the GA, and when I got up to the counter - I was delighted to learn that I was not only on the flight, but UG'd to FC as well (in an aisle seat, no less)!

Whoop, whoop!
