I actually have a LHR - IAD ticket right now for a separate trip in July, and I can't even see that there is any way to buy up. I can see where I can upgrade using miles and cash, but not the pure cash buy up. (It's grayed out.)

So, what I am wondering is:
- Is the cash buy up option just sometimes not available? Or do they just "activate it" closer to the time the flight is supposed to go?
- Is there any way to tell if there will be a buy up available in advance?
- Anyone have a ballpark estimate on what a 1 way buy up would be?

This is for business, so I don't want to use any of my personal miles.

Thanks in advance.
