I've just given up "Trans Ocean" after bringing it to 250 airplanes, somehow the challenge was gone. And the new 6.2 took the fun out of fine-tuning and micro managing the airline.
I was mainly operating in Beijing, Kunming and Shanghai Pu Dong. I just wanted to let you know that there are probably a lot of slots and unservered routes there. Don't let the big airlines take them away from you!
