Out of the Top 150 busiest airports, name either the city name or the IATA Code of the airport which lies furthest from the city center they are mainly serving to.
What about Frankfurt-Hahn (about 120 km from Frankfurt) and Memmingen-Munich West (about 115 km from Munich)? Or are we not counting the scummy Ryanair nicknames for airports far away from the actual settlement?
More examples:
Karlsruhe-Baden Baden
Venice-Treviso
London-Southampton (not used anymore)
Glasgow-Prestwick
Milan-Bergamo
Dusseldorf-Weeze
Paris-Beauvais
Paris-Vatry
Reykjavik-Keflavik
Brussels-Charleroi
Stockholm-Skavsta
London-Southend
Bratislava airport also was advertised as Bratislava-Vienna for a bit
I limited the quiz to include Top 150 busiest airports only, because there would be endlessly small airports lying +100km away just because one company named it so. I thought it would be less fun to guess Frankfurt Hahn, since no-one knows about the airport, over let's say the airports in London, Stockholm or Narita. People more likely know that they are located miles away from personal experience or research.
There is also an european version of this quiz linked in the caveat, which includes smaller airports
