It depends on what you want for a career path. Ask how much they fly, both hours per month/year AND days away, expenses. I know guys flying 8-10 days max per month and the plane only flies 175 hours per year (large cabin) paying 275k. Great job, but you’re not building time IF you want an airline path. Loads of great and not so great corporates, you have to know how to interview them as to what the operation is like.
Are the planes operated for charter? If so, lots of time away, lots of hours, likely little or no more money. Is it operated under a management contract or in-house department?
