Balewa,
I am a local flying corporate in Nigeria.Read your post and want to clarify some issues you raised.
Yes there is an increase in the number of private jets in Nigeria but most of these jets are here on ACMI and most of the operators signed a 6 months or one year lease contract for the machines.So the issue of employing locals does not arise IMHO.
There are about 5 major charter operators in Abuja and Lagos Triton/Hanger8,Izzyair,Prime Air,King air ,,vista jet,ACE.About three of the operators I listed don't have an AOC yet but are in the last stage of securing one.Those without AOPs normally use their registeration as call sign.
Express and C-express are two different entities.And both are used differently but most people think it is the same operator.
Some of the jets are here for short term contracts and I know a company in Abuja that leased 2 jets on ACMI for a year for their company ops.
Thanks
