Well, you've already got operations like PenAir and ERA doing a lot of flying to the bush out of ANC. AS is, at the moment, serving the larger destinations like BET, OTZ, OME, etc, and I wonder how many of those runs are still Combis.
But yeah, I think you're right. I'd be a little worried if I were PenAir or ERA.
Can a Q400 operate economically out of a 4,000 runway? If so, DUT may be in their future.
