I'm a line guy and was asked to be a project pilot, basically someone who works in DAL on office stuff. Once I was told the particulars I politely declined. I would have had to commute and the days worked for pay was no where worth it for me.
maybe if I lived in DAL and didnt mind working more days I'd think about it. If the instructor position is similar there is no way I'd commute to it. I'd only consider it if I lived there and had no way to continue flying or was retired and wanted to get out of the house.
