"Aircraft is not to be leased!

Sorry, your airline doesn't have enough money to lease this aircraft! "

I get this message when I want to lease a B753 for 10 000 000v$. My company has 12 000 000v$ but the system doesn't lease me the aircraft.

Tekin, you may be trying to buy an a/c for yourself instead of company.
Just to make it clear. Buy the a/c via fleet page of your company. Don't use the option Hangar which is listed under personal section.

(Selam Arslan abi),

I did try it from the fleets page, its not important anymore because I've leased a B752. But there might be a bug in the page.
