I will add a vote for USED TO be able to .. but no longer.
Did it back in 2001 time frame but have been told repeated that it is no longer available.
that is indeed the correct answer. one could probably even find the AA forum thread from 2001 when the practice was disallowed. by far the most popular usage was for 3-class transcon, where the J-to-F add/collect could fall well below $100 at times.
the first "vote" is describing the current last-minute-upgrades-for-sale practice, available seemingly at random on longhaul flights.
the last "vote" is either describing incredible marketing-department favor, or another airline, or a brand new world, or is in error. caveat lector.
