CO will not release F seats via EUA until it is pretty sure that it won't be able to sell them to someone. On EWR-LAS/SFO/LAX routes this pretty much guarantees that EUA won't upgrade you at the opening window,if at all. The DL Stupidfares which offer F for a fraction of what it used to cost don't help too much in this regard either.
