If I'm reading the schedule of UPS flights from Anchorage to Louisville correctly, flight 99, the continuation of the one currently in route from Korea to Anchorage, got delayed until 5:25pm AKDT, which I believe is about a 2 hour delay. I think it's because the flight from Korea left about 3 hours late. Two hours is probably enough time to scan the packages, refuel, maintenance, and change crews. Then off to Louisville.
God, there's too much info on the internet and I'm obsessed.
Personally: There's a flight that leaves Louisville for CID (Cedar Rapids), which is my local UPS hub, around 4:30am. Assuming the flight arrives in time, the packages get off in time in Louisville and transferred properly, mine could show up tomorrow.
