I have modified the London City airport (EGLC) to accept the larger planes ie: extended runway, added two new runways, added Large/Heavy gates and ramps.

I recently downloaded the FedEx and UPS BAE 146-200
package and set both liveries up as AI, have set-up flight-plans and everything - only problem is when I visit the designated aiports I can't find them anywhere  :(

Is there anything I need to do to make them work properly

Traffic is always at 100% so that's not the problem.

This could be caused by any number of things. I have those aircraft but i've never tried them as AI. They might not be suitable.
There could be a problem with your flightplans. I use AITM, it tells me if there is a problem when i enter my flightplans.
Believe it or not, there still might not be enough parking. If you have all the PAI airlines installed and havn't removed the default AI, your new parking spots may not be enough. Project AI has a remover that will take out ALL default comercial AI, or AITM will remove only the flights you choose.
