"Edinburgh Airport ( Scottish Gaelic:  Port-adhair Dhùn Èideann ) ( IATA:  EDI,  ICAO:  EGPH) is an airport located at  Inglistonin the  City of Edinburgh, Scotland. It was the busiest airport in Scotland in 2015, handling 11.1 million passengers in that year, an increase of 9.4% compared with 2014."

I think it's the busiest, but I chose Edinburgh because I've flown there but not Glasgow. Let's just say that EDI gave PyranAir a deal to fly there instead of Glasgow ;)
