If we want to judge by modern standards, the vast majority of relevant historical figures would look downright awful considering views and actions, but such an excercise has always looked mostly pointless to me (with a few notable exceptions). If the airport was named like that due to his accomplishments as a pilot, I'm not sure why it should be renamed due to his politics.
I generally don't like judging historical figures by today's moral standards. But even in the 1940's Lindbergh was largely accused of being a Nazi sympathizer. By FDR himself in fact.
