Glacier Park International Airport (FCA) in Montana USA is the best small regional airport I have visited. After a very long journey from Sydney we were cleared very fast. What impressed us was the security guard who stands on arrival exit door greeted us with a big smile and sad: "welcome to Montana". On our return flights we were checked in very fast cleared very fast with smiles by TSA (what a difference after LAX-TSA!). The terminal and toliets are very clean.
