I've tried 3x today to buy some tickets on delta.com but every time I get to the purchase screen I see the "Note: Verify the flights you wish to upgrade via the checkboxes next to the Upgrade Status column." message .... but there's no "Upgrade Status" column!

I've never run into this problem before. Usually the box is just auto-checked, or I can check it easily. What's the deal? I don't have the patience to call and deal with customer service on the phone. I checked in the "Advanced Search" option the "Request Upgrade" box......

Any tips/ideas/suggestions? I'm waiting 5+ minutes on the "Chat Live" function (which floated across my screen and I am using for the first time ever). Of course "Chat now" is not "chat now"
