I took another look at some of your pages and you have a terrific viewing site at the airport in Zurich which gives you lots of nice photo opportunities. The closest International Aiport here is KPHL but we have only a handful of International aircraft and no viewing site of them like you have. Other than kphl any International flights require me to drive to a location to see them.
A long time ago flew from Geneva to Nice but now only committed to memory. Take care. Clear Skies.

Thanks for the comments!
