I can tell you what the Fractionals pay, and they are like big corporate flight departments, in a sense: it's all on-demand type stuff, no operational control, but much of the same kind of work.
I know the boss of flight following at Avantair, and they have upped their
starting pay to $40k because they can't find anyone to work there, and the turnover rate is like that of burger king. There are many reasons for the understaffing there...
Netjets starts at about $38, but with superior benefits, and good opportunity for advancement.
If you want to hire good, experienced flight followers, don't pay them the meager wage of $28k and expect them to stay for much more than 6 months, esp. when there are plenty of corp. gigs that pay well.
