Other (and probably better) examples are "Oslo" Torp (Sandefjord) and "Hamburg" Lübeck... and of course the previously-mentioned middle-of-nowhere "Frankfurt" Hahn.
Though more recently FR seems to have started services to airports that it refers to by their real names - for example, there seems to have been no attempt to market services to "Hamburg Bremen" despite the fact that Bremen and Lübeck are equidistant from Hamburg.
Düsseldorf-Weetze also enters into the above category. I spotted a sign by the DUS taxi stand the other day listing the price for a taxi ride to DUS-Weetze as being €100 - € 105.
