Since 3-letter airport codes are so scarce they can be recycled one year after they are dropped. Case in point, when Idlewild Airport became JFK, the old IDL tag was retired then reused for Indianola, Mississippi. What other ghost airport codes around the world are currently finding a second life at another airport?

Quoting BlueBus (Reply 3): Some like JFK are obvious, but others like ORD are not.
It would appear that the ORD designator came from the fact that O'Hare Airport used to be called Orchard Field:
"Established in the early forties, O'Hare Airport began its life as an important regional manufacturing site for the Douglas Aircraft Company. In 1945, the airfield became known as the Orchard Field Airport (hence the code 'ORD'), only to be renamed again in 1949 after the famous US naval aviator Commander Edward Henry 'Butch' O'Hare."
