I know that it is very important to set up base in a good airport with good location and high PAX. But i think it is too saturated at some airports. Took one of my friend as an example. His base in Hong Kong. He have get an Dornier-100(or 200) and Helio H-600. It can fly about 700 nm. When he try to find for some routes capable for this two planes, it is very unfortunately that i can only find two good routes for his Helio (Please be noticed that the 2 routes are over 1000nm). It is even worst when he find routes for his Dornier. He have find out that there is no routes which suit him!( His Standard is quite high, no competion).
Although his target is too high, but he can still show me some fantastic figures for me. He said that he had find quite a few routes( which gate rent is 25000 or 50000) with 4 airline having competitions. I think it is quite imposible as i am in US. For me i can have no competions even i am in atlanta ( For some routes less than 600nm) The difference is too high isn't it.
