Salaries for a BE1900 F/O in Gabon:
Avirex: 3000 USD + car + telephone (they dropped their last 1900 less than a year ago).
Air Service Gabon: 4000 USD + accomodation (they dropped theirs about 18 months ago).
Air Affaires Gabon: 4000 USD + accomodation.
And as far as Angolese operators are concerned (SAL, Golfo and Sonair), I would be extremely surprised if they paid their F/Os less than 2500 USD.
