Named in honor of Colonel Harry S. Berry, state administrator ofthe WPA, Berry Field consisted of a terminal building, two hangars, a 4,000-foot concrete runway and a flashing beacon.The three letter identifier, BNA, stands for Berry Field Nashville.
Nashville International Airport: Established in 1937, its original name was Berry Field, from which its ICAO and IATAidentifiers are derived. The current terminal was constructed in 1987, and the airport took its current name in 1988. Nashville International Airport has four runways, the longest of which is 11,030 feet (3,360 m) long, a size adequate to handle all aircraft in service in 2017.
BNA is the 3 digit code that identifies the airport. Like LAX for Los Angeles, or DTW for Detroit.
May be from Berry Field Nashville.(Google) Barry Nashville Airport (just made up!!)
The original name was Berry Field Nashville, the military designation. The call letters BNA are based on that name.
It was a military base before it was Nashville Inl Airport in it's civilian life, and that was it's military designation It is now rare to see the "Berry Field" portion used, but the airport's IATA code (BNA) is short for Berry FieldNashville, and the military facilities at the airport are still commonly known by this name
