Chicago O’Hare International Airport Code, Map and Information

Airport Code

O’Hare International Airport: ORD

Fun Fact: Originally named Orchard Field, Chicago renamed it’s primary airport to O’Hare Field later on to honor the legendary pilot Edward “Butch” O’Hare.  Since the IATA code (ORD) originally represented Orchard Field, it has no relation to the O’Hare name or the City of Chicago in general, which is why the ORD code name is so confusing!
