Have a flight tomorrow, DEN-CVG, on a ExPlus CRJ700.

Did the check-in online 24 hours beforehand (right as it opened up), and was unable to pick a seat...

"Status - You are on the Departure Management list"

Just a regular economy fare, believe I'm fare class L, which I know is way down the list...do have a mileage plus card though (and checked in with it), if that's of any help.

Seat map shows that economy is full, but economy plus has a bunch of empty seats...

Any chance I'll get an upgrade?

Thanks!
