I've got the same problem. I've been expecting mine to hit Anchorage surely by now but I am stuck in this "delivery change requested" hell.
Update, mine is just now listing that it hit Anchorage, no updated delivery date yet however.
Fantastic! At least it's moving! Hopefully mine will soon as well!
Also, did you ever see a departure from Chek Lap Kok? Or did it just arrive in anchorage?
