Thank you guys so much for dealing with all my questions! It's seriously been a lifesaver. It's just been difficult for me to figure it all out since these benefits are relatively new to my great aunt and she never was taught how to use the online jet net stuff, since she originally lost her retiree flight privileges in the late 90's. You all have been so wonderful.

So where I check in (as early as 24 hours before departure) is the "Jet net Check-in" tab on the right column at jetnet? That seems like an obvious answer, but I just want to ensure I'm doing everything correctly. And I'm assuming I would want to do it ASAP too.

With the one flight to HKG a day, does that mean if 10 people from the day before (July 7th) don't make it onto the flight, that they would have higher boarder priority on July 8th than the people that had listed (and checked in) for July 8th?
