i see you have used textures from the Paris scenery and models FGFS.
You need to be very careful as to which you use as not all of them are GPL hence the reason why they arent all in the Official repository.
Some are classed as freeware and not GPL
"Though freeware does not require financial compensation, it does have a user license or EULA (End User License Agreement). Each license is specific to the freeware it is bundled with, but some restrictions are common to most programs. For example, most freeware forbids the user to alter the program, repackage it, or sell it. It might allow redistribution, however, as long as the program is unchanged and the license agreement intact."
My advice would be to check which of the textures are GPL and which aren't before sending them to Martin for the Official Repository.
The models are of course free to use etc for your own benefit (whoever downloads them)
That being said i have now dowloaded and the airport look very good!
