washington dulles international airport
sometimes, a new airport is built, replacing the old one, leaving the city's new "major" airport (or the only remaining airport) code to no longer correspond with the city's name. the original airport in nashville, tennessee was built in 1936 as part of the works progress administration and called berry field with the designation, bna. a new facility known as nashville international airport was built in 1987 but still uses bna. this is in conjunction to rules aimed to avoid confusion that seem to apply in the united states, which state that "the first and second letters or second and third letters of an identifier may not be duplicated with less than 200 nautical miles separation." thus, washington d.c. area's three airports all have radically different codes: iad for washington–dulles, dca for washington–reagan (district of columbia airport), and bwi for baltimore (baltimore–washington international, formerly bal). since hou is used for william p. hobby airport, the new houston–intercontinental became iah. the code bkk was originally assigned to bangkok–don mueang and was later transferred to suvarnabhumi airport, while the former adopted dmk. the code isk was originally assigned to gandhinagar airport (nashik's old airport) and later on transferred to ozar airport (nashik's current airport). shanghai–hongqiao retained the code sha, while the newer shanghai–pudong adopted pvg. the opposite is true for berlin: the airport berlin–tegel uses the code txl, while its smaller counterpart berlin–schönefeld uses sxf; the yet-to-open berlin brandenburg airport has the airport code ber, which is also part of its branding. the airports of hamburg (ham) and hannover (haj) are less than apart and therefore share the same first and middle letters, indicating that this rule might be followed only in germany.
