What Month In Bali is the Cheapest to Fly The cheapest months to fly to Bali are typically during the low season, which is from January to April and October to November. During these periods, you can often find more affordable flights and accommodation due to the lower tourist demand. Additionally, avoiding the peak holiday seasons, such as Christmas, New Year, and the Indonesian school holidays, can also help you find better deals. To get the best prices, it's advisable to book your flights well in advance and keep an eye out for any airline promotions or discounts.
