I have 250 planes, but my profit never exceeded 250,000k when I had less than 100 planes. Now when there is 150,000k it is very good.
My fleet contains various planes ranging from the 747-400 to the CRJ100, I also have some cargo planes.
All of my planes have fuel efficiency above 6.0
My employees are satisfied with their salaries
I was investing in the service level (now I am in an economic crisis and I can't afford a high one)
I have a hub in London (starting hub), Beijing (owning an airport), and Mexico (owning an airport)
I am adjusting the ticket prices almost every month (by "manage all route)
I invest in advertising in the cities where I have hubs (more or equal to 4 columns)
What am I doing wrong?
