which airport that Ryanair "serve" is furthest (or at least, most inconvenient to get to) from the town they name it after?
It occurs to me that I don't know. Cambridge (south) isn't in the running, as that's an official BAA lie*. Likewise they've stopped trying to call Bratislava as (just) Vienna, and despite being in a different country, it's more convenient than "Frankfurt" Hahn or "Dusseldorf" Weeze.
* just like "our core business is running airports".
