Space-available F cabin buy-ups for on short narrowbody flights are about $75-100 per segment these days. UA served up an offer of about $100 for a two-hour segment - and I was on an award ticket! (I declined.) The airlines are trying to find ways to get value out of the seats and they're finding that on many routes and aircraft types F isn't perceived as being very exclusive at all.

They're still mostly successful at preserving int'l C/F as an exclusive product worth a significant premium.
