It does not open until t-24 of your first flight
But say you have a two hour connecting flight to your second flight. At T-24 of your first flight you will also be checked-in for your second, T-26 for the second flight.
As I travel out of SFO, it is not uncommon to see folks checked in T-36 or more -- coming from Asia to SFO and then SFO to ??? I think I have seen as much as T-48 on rare occasions.
