Alaska miles can be worth quite a bit more than .02/mile. Depends on how adventurous you are.
My bucket list is to eventually book Seattle to a remote Alaskan village with stopovers in FAI or ANC, visiting the National Parks in Alaska (e.g. SEA-OME in June is $600-800 or 25,000 miles.
Then I need to figure out how to get to American Samoa using partner awards so I can visit the National Park there and then go on to New Zealand or Australia in Business Class.
Too many things to plan for.
