I chose the 777's because they will directly replace my DC-10's. I make nice profits off those DC-10's, even when the route only fills 120 economy seats. I have routes that fill 115 economy, 10 business, and 2-4 first and I make nice profits. Those DC-10's are configured to seat about 300! The 777, when compared with the DC-10, requires 1 less pilot, 1 more cabin crew, 1 less engine, and the engines on the -200 are more efficient and fly slightly longer - for almost exactly the same size aircraft (slightly larger, so I have premium business and first seats). The -200er model I selected has the cheap engines which burn roughly the same as my DC-10, but I'm not sure if the fuel usage is calculated per engine or is averaged for the aircraft so that may mean the 777 is cheaper there too. I've had good success with 777's before but have never used the Airbus for one reason or another.
