I am desperately looking to book by nov. 15th as well, but it looks like they only book 355 days in advance. If I book on the 15th, would I be able to book the first time up to @ nov 5th and then wait 10 days and try to rebook with a later date, up to nov 14th 2012?
My travel partner's dates are better from the 5th to the 14th.

Edit
I just realized the award program will have changed by then and probably will not include "legacy value" rebookings
