Always expect problems with JL when booking at the 331 day window. It seems some partners will not be available exactly at 331. For instance JL is only showing space through 9/22, i bet it has something to do with back when all the ~330 out booking went on hold, so they just pulled them all together from booking.

Seems there is some purposeful withholding going on with some of the partners as well for example QF is only showing though July 10th.
