Book Sumba flights 2–3 months ahead for the best fares, especially for peak season (July–August) and the Pasola festival period (February–March)
Fly on weekdays, as weekend flights might be more expensive due to high demand. Tuesday and Wednesday departures are typically the cheapest
Compare routes; flying from Kupang to Sumba is shorter and sometimes cheaper than flights from Bali to Sumba, especially if you’re already in Nusa Tenggara
Consider open-jaw tickets if island-hopping (e.g., fly into TMC, out of WGP or vice versa) to avoid backtracking.
Travel during shoulder season (April–June or September–October) for lower prices on flights, accommodation, and activities.
Look for promotional fares from Batik Air and Nam Air, since they often run flash sales on domestic routes
