Flights to Indonesia: When Are They Cheapest?

Most Expensive Time to Fly to Indonesia

Flights to Indonesia are most expensive during peak season, and are heavily influenced by both international tourism and domestic religious holidays, particularly when millions of Indonesians travel at once.

  • July – August: Peak summer season with high demand from European and Asian travelers.
  • December – early January: Christmas and New Year’s travel push fares higher.
  • Eid al-Fitr (varies, typically April/May): One of the largest travel periods in Indonesia; airfare spikes nationwide.
  • June (school holidays): Domestic family travel adds to international demand.
  • Easter (March/April): Regional travel bump, especially to Bali.

Cheapest Months For Flights to Indonesia

The cheapest deals on flights to Indonesia will fall during the shoulder seasons, since Indonesia doesn't really have an offseason.

  • February – March (before Easter and Ramadan): Off-peak travel season with cheaper fares.
  • May (after Eid al-Fitr): Airfare drops once the holiday ends.
  • September – November: Affordable fares after summer and before Christmas.
  • Early December (first half): Brief dip before the holiday rush.
