Sky Priority as an FO with no upgrade??
I just checked in for MSP-LAS tomorrow, and saw the "Now that you're checked in, be sure to use your Sky Priority benefits at the airport." Sure enough, my e-boarding pass has Sky Priority and Zone 1 on it. It's an L fare, no upgrade, and I don't a DL Amex or anything. And I'm only Silver.
So yea, that's weird. ^
