I recently completed a copywriting project that included a brochure about Florence, Italy. The brochure said that some visitors choose to fly into other Italian cities and mentioned a few airports: Leonardo Da Vinci International Airport in Rome, Guglielmo Marconi Airport in Bologna, and Galileo Galilei Airport in Pisa. I was awestruck by these heavy hitters -- Da Vinci, a true "Renaissance man" of art and science; Marconi, the inventor of radio; and Galileo, one of the ten most famous scientists of all time. Just for kicks, I searched online for more Italian airports and found Venice (Marco Polo) and Genoa (Cristoforo Columbo).
Then I thought of the United States. Atlanta's airport, now the world's busiest, is named for two former Atlanta mayors (William B. Hartsfield and Maynard Jackson). Chicago's airport is named for a minor World War II hero (Butch O'Hare), while Boston's airport is named for a relatively obscure general (Edward Logan). Houston's airport is named for a forgettable president (George H.W. Bush), and Washington's airport is named for an overrated twit of a president (Ronald Reagan).
Italy's airports are named for enduring giants of history. Ours are named for politicians. I doubt that any of America's airport namesakes will be heralded in history books several hundred years from now (no matter how much other crap the Ronald Reagan Legacy Project gets named after the B-movie actor).
Note: One could argue for Wright Brothers Airport, but that's in Dayton, Ohio, hardly a major destination. Plus it's not even the biggest airport in Dayton (which is named for a former Ohio Governor).
