After a couple years of being plat, you maybe should have known that LAX/SFO-EWR isn't a CPU-able route? Otherwise, what would be the point of those RPU's? Or what's the point of "PS".
So you think being able to upgrade a 600-700 economy ticket to a lie-flat business ticket for a 12-14 hour flight is worthless? Um, there are dozens here who would happily take those worthless GPU's. Not worthless IF (and a big IF) it clears. Look at the delta pricing between economy and business.
