Hey
I have read some topics about tips and advices but idk why they are not working with me. my airline is still losing money even if I am operating only 2 Boeing 737 from Chile to Argentina and the flight is almost full and 1 DC-7 to Sao Paolo and my airline DOP is almost 330k but I am still losing money every new month. I think the fuel and maintenance are the reason so what should I do to build a good airline?
like what aircraft should I lease or what should I do to earn money? I have tried like 3 worlds and still losing money so any help and advices?
