In my experience asking about QOL for an air ambulance job is akin to asking how to retain your virginity while doing porn. The equipment is usually crap, the pressure to fly is intense, and the medics think they run the show. And all that for $60-75K a year. Sorry, but that's crap.
My fourth year with the airlines and I made a little over $200k last year averaging 10 days flying a month and I flew a little under 280 for the year. My advice is to skip the clown show and get paid. Money and time off do buy happiness.
