In Europe, the convenience/inconvenience of airport locations varies a ton (which does influence purchase choices somewhat). For example Frankfurt's airport is only 8 minutes by commuter rail from the city center, and Copenhagen's is 12 minutes. But Paris-CDG and London-LHR are far from their city centers.

You still have to trek through the airport, wait in security lines etc etc. so in reality it takes much longer than the time it takes the train to travel from the airport to the city. That said flying is often if not nearly always cheaper for short hauls in Europe.

and Oslo is so far it doubles if not triples cost of your cheap plane ride (30 bucks for train ticket between city and airport)
