I can promise you right now that they will not put a 300hr pilot into a caravan flying into the delta.
1) You would not have seen the type of flying that they do there before. They are not going to stick you out there in the flagship aircraft.
2) There are other pilots that have been there and done their dues for a year or more. There would be a riot.
One of the companies there recently poached caravan drivers from other companies to immediately fill some positions. The pilots that were approaching 1000hrs were furious as they now had to wait nearly one more season before looking at the left hand seat of the caravan.
3) All of the companies that I know of require 1000hrs and experience in the delta as part of their insurance requirement.
Pick your choice of the above reasons. Its not going to happen.
