Probably make triple, but it's a different life style  

1. Airlines - You get to make your schedule (once you get a little serniority). You fly a lot more, but it's for the most part, pretty easy flying. Much safer than HEMS...as far as accidents go. Not sure about the other health consequences such as overnight, choice of meals, exposure to a lot more people

2. Corporate - You don't make your schedule, but you fly a lot less, but depending upon where you go to, you may spend a lot of time at remote locations - This is for some people, but not for others

3. 135 - Not my cup of tea. Fly your tail off, but at least you get a lot of FW experience in a lot of locations etc
