There's a lot more to life than simply compensation.

I made the jump from a light cabin 91 job to a major carrier a year and a half ago and have no regrets whatsoever...but not everybody flying corporate has a personality suited for 121 operations and the quality of life aspect MUST be considered.

I will say I have noticed 91 salaries going up over the last few years, but more than that, a lot more movement between operators. Of course Jet V has enjoyed job portability unmatched by Jet II/III pilots, but even mid and light cabin pilots are starting to be "recruited".
