Update to this thread:
The Anchorage Daily News just ran a pretty comprehensive article on what is required to be let into Canada through to Alaska *by ROAD*:

... I imagine that things will be similar for going through by GA. The bit about "only having 24 hours to get through the Yukon" has me a little worried, weather being what it is...
A few weeks ago, I talked to a human at Canada Border Services, who verified that yes, "An Alaskan returning home can fly through the country"; this does qualify as essential travel. Be prepared to show something like an Alaska drivers' license. Things like "going to my cabin" and "visiting a relative" do *not* qualify. She also told me "the rules might be changing on June 21, so call back sometime after that." My trip will be in late July, so I'll be calling for that update, and will let y'all know what I find.
If you're arriving by commercial airline to Alaska from anywhere, there are now a few different "test at the airport" or "test before departure" options that can let you cut your 14-day mandatory quarantine shorter. Looks like they're *not* going to be doing this at the Alaska/Yukon border at Northway, so I'm hoping they'll let me fly straight to Anchorage to do my 14 days at home.
If you're thinking of making a trip like this, PM me if you want to know the phone number for Border Services, where I managed to contact a human after many failed attempts at phone trees. (I'd post it here, but I left it in the plane.). I'll also update this thread if I find out more.
