Expertflyer is showing 0 V availability, with 0s in economy and 9 P. It doesn't appear that the seat map has changed in the last few days. As a newly minted silver, (still waiting for my bag to wear over my head to show up in the mail) does this make sense? Is it possible that Y is overbooked and DL will just process upgrades at the gate? Or is it possible that the only people on this flight (DTW-MCO) that would be upgraded are silvers w/companions? F shows about 20 open seats.....
