I'd reply to the head hunter if you're interested. They'll have the details.

I was contacted by a headhunter about a different job. About 1+45 hrs away. Part 91. Two guaranteed days off per month. "But you'll fly less than 15 days a month and the schedule is fairly well set a couple of weeks beforehand....except for the occasional pop up trips." So on call 28 days a month except for the roughly 50% of the time you're flying...
