Frans Xavier Seda Airport (IATA: MOF, ICAO: WATC, formerly WRKC) — also known as Wai Oti Airport or Maumere Airport — is an airport serving Maumere, the capital city of Sikka Regency and the largest town on the island of Flores, in the province of East Nusa Tenggara in Indonesia. Maumere is known for its reefs in the Gulf of Maumere which were once considered some of the finest diving in the world. The airport is named in honor of Frans Seda (1926–2009), who is a former finance minister of Indonesia.
