I've been flying medevac here in AK for 7 months now, love it! From what I hear, the airmed field used to be a lot of small companies competing against each other, now it's a couple bigger conglomerates. This is good for all involved, as the bigger groups have more financial depth, better pay and bennies, less pressure to take every flight, etc.
As a KA200 captain, I'm making about $100k a year, with the ability to work more at a substantially higher rate, occasionally. I'm away from home for 16-17 days a month, but it's a very easy schedule, and sometimes I time out at my home base , so I sleep in my own bed 2-3 nights per shift. The company expects you to do the right thing, so I have only turned down flights when the weather was truly atrocious, or we just couldn't make it work with duty day, etc. This is night and day different from flying 135 cargo in a beech 1900, that job was brutal. So far, I'd say this is the best balance of work/pay/quality of life that I have found in aviation.
