São Tomé International Airport

São Tomé International Airport carries the IATA code TMS — the three letters printed on boarding passes and baggage tags — and the ICAO code FPST, used in flight plans and by air traffic control. It serves São Tomé, São Tomé and Príncipe.

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.
