On a recent flight from BOS-SFO-SYD, the BOS-SFO leg was delayed so we spent the night in SFO, and had to check into that flight the next day. We decieded to check in early to change some seats around.
The SFO-SYD next flight didn't depart until 10:40pm, but we checked in at about 10:00am just fine. So same day, 13 hours early worked ok, with checked bags.
Gave us a day in San Fransisco already knowing that we were all set at the airport.
