All I could say is that cutting costs in AM through cutting leases is a waste of time.
If you get 12 million monthly DOP on a 5 million leases, for a plane worth 50 million to buy, you get 7 million out of that lease.
If you buy a plane to replace the lease, you pay out 50 million and still earn 12 million.
If you keep the lease but buy a plane to expand, you pay out the same 50 million, but earn 19 million.
If you use the same 50 million to lease more plane, you get 10 more leased planes, earning a total of 77 million.
Which has a higher profit margin? Replacing the lease.
Which has a lower cost? Replacing the lease.
Which give you more profit? Lease more planes.
Which would help you grow quicker? Lease more planes.
This is the exact reason why businesses mortgage / finance / take out loans. They have higher costs in terms of $$ (and usually % as well), but they have a lot better return on investment, and they don't tie up their cash in one place. Financial leverage is essential if you use return on investment as a guideline, which really, is the only all-round benchmark to use.
Oh, and yourefired, there is no use calculating the average to find a proportion. All you need to do it look at your finance page for the total costs and the total revenue (or if you insist on using DOP, which doesn't make sense from an accounting pov, DOP*24), you could figure out that % you want. (<-- managerial accounting, which is only 9 cr. hr. of my major, always beats economics

(- The above scenario does not take into account gate rents and salary, because assuming that they are fixed costs, they would take up the same proportion of the revenue in all the planes, and thus do not affect the comparision.
- The above scenario does not take into account maintenance, but maintenance give advantages to leases because the plane owner pays it instead of the operator, and thus further increase the difference in between the cases.
- An assumption on the above scenario is that the leases are actually making money. If they are not, why the hack are you even thinking about keeping them? )
