Taipei Songshan International Airport

Taipei Songshan International Airport carries the IATA code TSA — the three letters printed on boarding passes and baggage tags — and the ICAO code RCSS, used in flight plans and by air traffic control. It serves Taipei (Songshan), Taiwan.

IATA codes are assigned by the International Air Transport Association for passenger-facing use; the four-letter ICAO code encodes region and country and belongs to the operational side of aviation.
