Ok, your post made me curious, so I just checked in for my flights tomorrow. My wife and I (exit row) both got Zone 1 with no Sky Priority. I'm a Silver, she is just a general member. Another interesting thing is that I have the DL Reserve card and I don't see 'Expedite' on mine either. I wonder if they are working with the systems to get ready for the new AMEX boarding benefits, which I think are supposed to take affect in September.

Either way, I'll hit GM on this trip, so I can join the group who is angry that these lowly FO's have been clogging my Sky Priority lanes!

EDIT: Just checked 'my trips' on delta.com and I see the Sky Priority banner. My guess is that they are doing work on the systems. I'll reprint my BP at the kiosk tomorrow and see what I get.
