Quick question: I'm on F9 DEN-BNA on 2/7/10 with spouse as Classic. We selected seats upon purchasing tickets but I'd like to see whether others are available - seeing no option at all on Frontier's website to change assignments.

Seems strange. Any 411? I'll pick up the phone, but I know Flyertalkers are better sources of info in general...

Update: Called. You can't change them, or view the seating map, online. Seems sort of luddite of F9...
