Airfields already in regions won't be done as freeware. as well, I would doubt that airfields included in the excellent Tongass Fjords would be either (not an orbx product, but developed by current and former ORBX devs for fsaddon, and very useable in v4 with the right installation steps) TF covers Klawock, Wrangell, Petersburg, Kake, Sitka, and Hoonah (and Sitka and Petersburg are very well done in full by Bill Womack) ORBX SAK already has Elfin Cove, Haines, Skagway, and Merrill. Also, If I'm not wrong, King Salmon has already been released in a freeware pack.
My humble Alaska request would be for PACX Coldfoot and anything nearby in the Brooks Range
