Most profitable route from Bari?

I currently have a lot of airport keys lying around in Bari, and I wanted to see what’s the most profitable route to open. I’m considering Jakarta solely because of the amount of fuel, but the L aircraft Paris and London flights are interesting as well.

Thoughts?

I send the L planes on routes of about 4 to 5 hours atm. So ADD would be an option. But maybe others know better routes.

I have done some charting in spreadsheets…
I found out that the shorter the flight time, more money you can earn
But that is if you always immediately handle the plane… It depends on your daily schedule

Sometimes I play literally all day with small breaks, I earn more
