I missed my flight and they put me on the next one. I didn't have a seat assignment on the full flight, only a seat request, but got an upgrade anyway at the gate (so for anybody who thinks Diamond status isn't worth it, think again). I lost my upgrade on the second flight, too, and am hoping to get an upgrade on my new flight, which I also only have a seat request card for. I can't see the upgrade list because DL website is telling me I'm not checked in (even though I'm in flight using gogo to type this). There is a check in button. it is taunting and teasing me. I am feeling a compulsion to click on it so I can see where I am on the upgrade list. What will happen if I do? Is this one of those things where it will screw up my whole reservation or will it just do nothing (since I'm already checked in and in flight on my first segment) and let me see the list?
