Several airports in the United States are already named for former Presidents and other prominent politicians:
ANC - Senator Ted Stevens ATL - Atlanta, Georgia - Mayor Hartsfield and Mayor Jackson CLT - Mayor Douglas DAY - Gov. Cox of Ohio DCA - Washington, DC. - President Ronald Reagan Airport GRR - President Gerald Ford HOU - Houston, Texas - William P. Hobby Airport IAD - Washington Dulles Airport - Secretary of State John Foster Dulles IAH - Bush Intercontinental Airport - President George H.W. Bush JFK - NY JFK Airport - President John F.

In many cases, the official airport abbreviation does not appear to match the name of the airports. That is because most of these airports previously had different names. Many of the airports originally had the name of the nearest major city, or were military air fields.
