Cheapest Time to Fly to Bali (and the Most Expensive)
The cheapest time to fly to Bali is usually late winter and shoulder-season weeks—while summer and late December are the priciest.
Bali flight prices can swing a lot by season—mostly because demand jumps hard during summer vacations and year-end travel.
If you’re flexible, you’ll usually find the best deals after the New Year rush, during shoulder-season weeks in spring and fall, and in early December before holiday pricing kicks in.
Quick Take
- Cheapest time to fly to Bali: late January–March, April–early June, September–early November, and early December
- Most expensive time to fly to Bali: late June–August, late December–early January, and peak holiday weeks in spring
Cheapest Time to Fly to Bali
The cheapest flights to Bali usually show up when fewer people are booking long-haul trips, airlines have more open seats to fill, and you’re outside the big vacation windows.
Late January to March (Post–New Year Dip)
After the year-end rush fades, airfare often cools off—especially once people are done traveling for winter holidays. This is one of the more reliable windows for lower-priced itineraries from the US.
Money-saving tip: If your dates are flexible, try leaving on a Tuesday–Thursday.
Exception: Some weeks can bump up if a major holiday lines up with school breaks.
April to Early June (Spring Shoulder Season)
Spring into early summer is often a sweet spot—good deal potential, and demand hasn’t fully shifted into peak summer pricing yet. For a lot of travelers, this is the best mix of price and comfortable conditions.
Money-saving tip: Compare a few nearby departure airports—sometimes a short domestic hop knocks a big chunk off the total fare.
Exception: Late May can run hotter on pricing if it overlaps with US holiday travel.
September to Early November (Post-Summer Cooldown)
Once summer travel winds down, fares often loosen up again. This is a strong window for deal-hunting because demand is usually lower than July and August, but flights are still widely available.
Money-saving tip: Look at slightly longer connections—Bali deals often hide in itineraries with one extra stop.
Exception: Late September can spike if it overlaps with popular school break weeks.
Early December (Pre-Holiday Lull)
Early December is often quieter before the late-December travel rush. If you can fly before holiday pricing kicks in, this can be one of the best “deal-friendly” windows of the year.
Money-saving tip: Keep your return flexible—late-December returns can jump fast.
Exception: The closer you get to mid-to-late December, the more pricing starts acting like peak season.
Most Expensive Time to Fly to Bali
The most expensive time to fly to Bali is when US vacation demand overlaps with peak travel seasons to Southeast Asia—fewer flexible seats, higher price floors, and fast sellouts on the best routes.
Late June to August (Summer Peak)
Summer is usually the priciest stretch for long-haul airfare. More families are traveling, more people need weekend flights, and popular routing options get booked quickly.
Peak within peak: Late July into early August is often the toughest stretch for deals.
Late December to Early January (Year-End Travel)
This is the classic “everything costs more” window. Christmas and New Year travel pushes up fares across most international routes, and Bali is no exception.
Peak within peak: Late-December departures and early-January returns are usually the highest-priced combos.
March to April (Spring Break Pricing)
Spring break weeks can quietly drive up Bali airfare—especially if your dates line up with school schedules and high-demand weekends.
Peak within peak: Friday/Saturday departures and Saturday/Sunday returns tend to price higher than midweek.

On a Budget But Want Good Weather in Bali?
If you want solid weather without peak-season airfare, these windows are usually your best bet:
- April to May: Drier days, better deal odds than summer, and fewer date-specific price spikes
- September: Great timing after summer travel fades—often one of the best value-weather months
- Early December: Comfortable trip conditions with prices that are often lower than late-December holiday travel
Best Booking Window for Cheap Flights to Bali
Because Bali is a long-haul trip from the US (and often involves at least one connection), pricing can move fast when a good fare drops.
- Low/shoulder seasons: start tracking 2–4 months ahead
- Popular seasons: start tracking 4–6+ months ahead
Extra tip: If you can fly midweek and avoid tight layovers, you’ll usually see more “good option” itineraries at better prices.
