Plenty of airports around the world retain their old IATA codes even after changing names. This practice extends to some railway stations as well. In the United States, several airports have obscure codes that trace back to historical reasons.

IATA airport codes are challenging to change once assigned, requiring strong justification for any alterations. A spokesperson from IATA explained, "IATA airline codes cannot be changed unless there is a strong justification for such a change. Request for changes should be made through the IATA customer portal at www.iata.org/cs with a detailed explanation on why the code needs to be changed. IATA cannot entertain requests for changes for improvement in marketing or branding of the airline."

These codes are crucial as they form an integral part of the travel industry's infrastructure and systems. As stated by IATA, "IATA Codes are an integral part of the travel industry and essential for the identification of an airline, its destinations and its traffic documents."

One example is Chicago O'Hare International Airport with the code "ORD," originating from its former name Orchard Field Airport during World War II. The airfield was named after Edward "Butch" O'Hare post-war but retained its original code.

The US Navy has reserved all codes starting with "N," preventing civilian use of such identifiers within the United States. This regulation explains why Newark Liberty International Airport uses "EWR" instead of a code beginning with "N."

New Orleans Louis Armstrong Airport adopted MSY based on Moisant Stock Yards due to this restriction, while Nashville chose BNA from Berry Nashville Airport's original name.

Originally using two-letter codes in aviation's early days, airlines switched to three-letter designations in response to increased air travel demand and potential confusion. For instance, Los Angeles International transitioned from LA to LAX in 1947.

Canadian airports present unique cases due to historical radio station coding practices: Montreal-Trudeau became YUL by adding a confirming 'Y' prefix indicating proximity to a weather station radio tower.
