Off the top of my head I can't think of a single operator that has any kind of a contract or bond for a 206/207 in AK, although ppragman is much more in tune with that world than I am these days. A three year contract is plain ridiculous.what are the contracts like at "similar" bush flying jobs up in AK?
What's your total time and 206 time these days? If you're near 1K TT with the right to work in the states you should make your way up there if you want to fly bush type flying.
