I'd think if you already are in Alaska, that you're fine. It's the Shanghai to Anchorage part that I think is disrupted.
But looking back a few pages, this thing erupted on June 15th or whenever, and people have had their tracking list flights from China to Alaska on the 17th 18th and 19th, so wtf Apple?
Are orders to the UK affected by this? Sorry - don't know where Anchorage is
