Most of the articles I found on Google discussed upgrading with miles rather than cash.
On my previous trips, I had to wait until I was airside and go to the customer service desk and pay to be put on the upgrade list for F when I would gladly pay up front to be confirmed in F
You can definitely buy up afterwards, but there are catches. AFAIK, you're not actually buying an F ticket, just the right to sit in F on those particular flights. If you have to change flights due to weather or something, you could end up back in coach with little or no refund. The other problem is that there's a lot of variation in those offers. F might cost $200 more at booking, but the buy up (FCM) price might be $500 or could be $100. A cleaner way to do it would be to call in during the first 24 hours and just pay the fare difference to actually be rebooked in F. That's more of a grey area though because they're actually issuing a different ticket than what the company bought. I would call your travel office and make sure they are OK with that before I tried it.
