The main difference between LEA and Blink is that LEA is a well established charter operator who did not claim to change the world but just that the Mustang is an aircraft that moves some Kingair Customers to Jets. As far as I know most of the LEA aircraft are privately owned... and the orderbook is less than 45

George Galanopoulos, LEA’s managing director, is delighted with aircraft’s introduction. “The Mustang is ideal for customers who travel in small numbers and want to upgrade from a turbo-prop without paying a premium. It is also proving attractive to existing jet customers, who may not always need the extra capacity and cabin space of traditional entry-level jets.”
