Hyatt has tightened up on extensions. When I first started earning FFNs, I remember being allowed to use them as much as 2 months out (diamonds only). Then it became one month. Then, during the last period, the one month extension was allowed, but only within the last month of the scheduled redemption period.

I am hoping that Hyatt will allow extensions into the first two weeks of March, but am currently holding the hotels I need with points.
