I guess it's possible, but nobody on the 1P line ever saw anything out of the ordinary.

Regardless - I'm 100% positive of my experiences on the evening sweeps moving me back to E- (I even reviewed the PMs with that FTer). In reading those PMs, I also confirmed that I was told by a UA supervisor that I was "entitled" to E+, but under airport control and of course based on availibility.

I hope that if the OP books the US stock, they report back their experiences on trying to move to E+.
