Aloha all, I'm trying to get clarification that seems obvious but isn't. When trying to book ANA Award flights, I know it errors out saying you can't book after it's within 96 hours of the flight time of the initial flight. But 96 hours on who's time?

Flight leaves 11:30AM Hawaii Standard Time on 4/22 from Honolulu
It's currently Thursday, 4/18 at 10:22AM Hawaii Standard Time (so 97 hours and some change...but to be fair it was also not showing two hours ago).

So why is it saying it's less than 96 hours? I can only book for 4/23 now.

So how do you figure out what's 96 hours before when the cutoff is for booking?

Anyone know?
