HNL-SFO redeye tonight, connecting to SFO-ORD-PIT. All upgrades confirmed with one CR1

. Checked in last night without any issue.
HNL-SFO was rescheduled to depart before the conversion, and hopefully everything is fine when I arrive in SFO at 3:45am

! Any idea what to do at that kind of time other than trying to reprint my boarding passes???
