I'm nearing the end of a round of an online game, Airline Mogul. My airline has hubs at Norfolk, Oklahoma City, and Portland, OR.
Being a hub airport not great enough for Norfolk? What would have the Norfolk Airport Authority salivating is that I have nonstop service from Norfolk to 15 cities in Europe: Amsterdam, Barcelona, Dublin, Dusseldorf, Frankfurt, Helsinki, Kemi (of course!), London - Heathrow, Madrid, Milan - Malpensa, Munich, Paris - Charles De Gaulle, Rome, Stockholm - Arlanda, and Vienna. I would love to have Athens, but the Ilyushin - 76 TD doesn't have the range to fly ORF - ATH nonstop.
