So with some A320s having 12 and others still having 8 FC seats, about how many days before does one know which one they will have? I know it could always change until last minute. I'm kind of hoping for a switch to 12 cause I'd have a much better chance of an upgrade clearing on SFO-BOS next Monday red-eye. Right now I'm looking and I see tonight is 12, Wednesday is 8, Thursday is 12, Friday is 12. I think they put the 8 seat as a placeholder for all Airbus flights until closer to departure date, correct?
