There was a flight from Shanghai to PANC, arriving PANC 10pm AKDT, that was four hours delayed. I think the consensus over in the other thread (Stainless Steel Space Black Shipping Status) was that those showing the exception should be on that flight. Keep an eye on the UPS tracking page for updates tonight. As long as it makes KSDF Sunday (or early Monday AM), it should reach local distribution points in time for Monday delivery.
Don't quite get how they update delivery times. Mine was Monday EOD until it reached the destination distribution center (KONT), now it shows as "unavailable". Not too worried about it getting here Monday, though, as it's just a few hours drive away.
