Yes, it's able to make it in that time, sure. However, that doesn't take into account clearing customs, which can be problematic. I don't claim to be an iPhone tracking expert, but i find it hard to believe a phone is going to leave China, make it to Alaska, clear customs, fly to Louisville, then get re-routed to the destination city and delivered in 2 days. I suppose 3 days is feasible and doable, but i just don't see it happening.
My Wife's iPhone would disagree with you
