what will happen, if i put in 20 772 f.e.
will there be added to every a/c group a million per month ?

Can't say exact sums but not bad since your fleet is already so large and so few types.

As long as you dont have something silly like ten planes and 5 fleet types, I don't think commonality matters too much. Recently I got rid of my BAC 1-11's as I had 4 other fleet groups, and the costs for the other groups went up?! 

[THI]

come on sami. make it +/- 20%
i just need a number which is realistic.

you see i learn to understand your code a bit

Just get a cheap little plane for a one year lease .. the cheapest you can find..

then check the cost and post it again, after that you just cancel the lease of the very cheap plane.

That will give you an idea

You're at about $7.2M right now.

My bet is that you when get a single 772, that will jump up to about $10.5M.

Anybody willing to spend money from his airline to do an experiment on this? It would be great if we know how the calculation of fleet commonality work.
