I used a relative's expiring voucher to upgrade today HPN-ATL-HOU; it turned out that I didn't need to spend her credits - 7 empty Biz Class seats on HPN-ATL and 2 empty seats ATL-HOU. I was pretty sure that I could have gotten free upgrades, but I figured that I might as well insure that I did since the voucher only had a couple months left.

cooger - I have only received auto-upgrades a few times since elite upgrades were introduced; congratulations on your record!
