Hey, So on Tuesday, I'm flying to SFO from DCA through Charlotte. The UG cleared from DCA to CLT, but not from CLT to SFO. When I checked EF, it looks like there's 1 seat blocked and two open It's US 1485 and I am not sure if they're holidng the seats for paid upgrades. Any ideas? I have an exit row in Y, so I'm not going to be devastated, but I sure would appreciate the bump.
