I just made a new reservation on united.com using my onepass number... for travel in January.
As many of you know the website still wants to charge for E+, so I picked E seats.

Then I went back at checke my reservation 20min later. For the two segments with E+ and F seating... it now reads:

Seats:
Flight: Confirmed
Upgrade: Pending
23D

and similar for the second segment (13D instead of 23D).

What does this "Upgrade Pending" notice mean? Have anyone seen it before? One could hope that it means that the system automatically will put me on the upgrade list.
