One which should surely be near the top of the list is Eleftherios Venizelos, the airport for Athens.
When it was located south of Athens, it was simply known as Athens airport, or Ellinikon by the locals.
When the new site was proposed, and construction began, there were many who wanted to call it Spata because, arguably, that is the nearest town and the name is well-known around the world. Apparently, the politicians became involved, and overruled all objections in order to call it after someone who had made a large contribution to Greek aviation. Very laudable, but I've yet to hear an arrival announcement on any airline other than Olympic which mentions the airport by name!
