It's impossible to compare a corporate job without more details...

Corporate jobs run the gamut from 6-figure lifetime employment on a G-something down to 24/7 booze-free pager duty, routine FAR and safety violations, jerk boss, etc, etc.

Also I have concerns when I see a junior pilot (cfi or regional FO) get a "sweet deal" corporate offer...if it's such a sweet deal where are all the experienced, typed corporate pilots? Either the pay is too low for them or the working conditions are poor.

Of course you might have lucked into a good opportunity, but do your homework.

Palin doesn't like Beech jets. If she becomes VP you can expect her to have all of them sent to Arizona to collect sand.

See if you can do some unpaid leave and try it out. It might be a little underhanded to try out the Beechjet job while keeping the airline in your back pocket, but corporate flight department are famous for pulling the rug on pilots. I knew one who had flown for an individual for 20 years and then he got dropped without warning at 50 years old because a local 135 offered to staff the plane in return for the use of the plane, plus income. It was in the fall before Christmas too.
