I just booked a YVR-SFO on this FP 7 days out, and the flight's already J0.
So keep in mind that while you're extremely likely to get J with this pass, it is absolutely not guaranteed.
I'm currently waitlisted for an eUpgrade, as I find that even when a flight is Z0, as SE booked in full Y, they tend to clear in the background. Though this obviously assumes there's J space.
I won't fly Y though. So either I change flights, or J opens up, or I cancel the trip.
If you need specific flights at specific times, you could run into issues.
