Simias,

Can you provide some additional info? Type aircraft, location, size of the department, etc? 100% Part 91?

Corporate gigs will vary greatly. My current job flying a Citation Encore part 91 includes salary, profit sharing (company-wide plan), 401K match (between 75 and 125% depending on longevity), standard medical/dental, education reimbursement, and travel expenses (vs per diem), among other things.

Be sure that you get a good written job description so that typical "extra duties" won't surprise you if there are any (for instance, at my company the pilots are required to perform basic interior and exterior cleaning and office duties, among other things.

You might also ask about what the typical "good year" pay increases are like and when they are given (for example I've averaged about 6.5% increases a year and salary reviews are every February.)

Some other things to consider: Training contracts, signing agreements/bonuses (rare), moving/relocation allowances, guaranteed days off, vacation/sick time, personal holidays, company holidays, overtime/holiday/weekend pay potential.

Finally, be sure to get as much as you can in writing. IMHO, any formal job offer should at the very minimum spell out any training commitment, salary, benefits, and job description.
