Bonaire is one of the Dutch Caribean islands.
You are probably refering to the new Bonair Exel. This is a new feeder for KLM, flying between Curacao, Aruba and Bonaire.
This used to be done by the now bankrupt ALM.
Bonaire is now the major hub for KLM in the Caribean.
I don`t know what type they use, or how the management is.
