So your saying that IATA interpose themselves between an Airline and an aircraft provider no matter what the commercial deal.
I can understand your point of Solomons selling a seat or any number of seats and strategic being member of the IATA dealing process and being paid for that seat.
I cannot understand IATA being a party or exposing themselves to what could be a non commercial/viable charter arrangement. It presents them to enormous risk.
I know some people at IATA, I'll see what I can find out and come back. There must be more to this type of transaction than is apparent.
Thanks for the info.
