Thanks for the compliments about our airport.
All buildings are through the Herpa Airport Set a la modified.
The international terminal has not opened as of yet, still under construction. But it is intended to be international and transborder. Mainly wide-bodied jets.
The look is an open feel, we modeled it sorta after Atlanta and Denver for the Domestic area and International was a sorta like Amsterdam.
Herpa has great gates, the buildings are fun if you modify it to meet your needs and not use the pre-existing formats and layouts.
