The pay for Flex pilots probably won't go down since we all know that flying a "luxury" business jet from from PBI to TEB takes more skill and is more demanding then flying a "value" business jet from PBI to TEB.
Just look at the Flight Options Phenoms and Net Jet Phenoms. The Netjets platinum edition phenom pilot deserves to be paid 40k a year more then the Flight Options origional version phenom pilot should be since after all the platinum edition has a more impressive sounding name.
Just ask Flight options management they will explain it to you.
