When this route gets cheap.
Fares bottom out in February around $1,091 and peak in October near $1,322, 21% dearer, across the 4 months we track. The cheapest itinerary we are tracking makes one stop and takes about 23 hours outbound, on a 15-night trip — ticketed under Korean Air, which on a connecting fare need not operate every leg. At $1,091 for 16,219 km each way, that works out to about $34 per 1,000 km flown. That is below the $42 per 1,000 km typical of ultra-long-haul fares here. Across the 18 departure cities we track at a similar distance from Bali, this fare ranks 14th — 1.8× the $596 we hold from Paris. That puts it in the cheaper half of the 18 routes of similar length we watch out of Boston, where the middle fare is $1,188. The best time to be in Bali: Apr–Oct.

Good to know
BOS → DPS, answered.
Is $1,091 a good price for Boston to Bali?
Only slightly. The seasonal median is around $1,195 round-trip and this fare is 9% under it. We do not call a drop notable until 20%, so this is an ordinary price for the route rather than a reason to hurry.
What is the cheapest month to fly from Boston to Bali?
Across 4 months of cached-fare history, Feb comes out cheapest on this route. The best months to actually be in Bali are Apr–Oct — when those overlap, that's your window.
How far in advance should I book BOS → Bali?
We do not publish a number for this, because we cannot measure it yet. Answering it honestly means watching the same departure date on this route over many weeks as it approaches, and that archive is still filling up — so any "book N days ahead" figure here would be borrowed from somewhere else rather than measured. What we can measure is which month is cheap: across 4 months of cached fares, Feb comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.
Are there nonstop flights from Boston to Bali?
The current cheapest fares involve a connection, ticketed under Korean Air. We hold no nonstop fare on this route right now, which does not mean none flies — search your exact dates to see what does.
Are these prices guaranteed?
No — these are cached fares found on real searches (this one on 17 October). Airlines reprice constantly, so the booking search re-checks the live price before you pay. Fresher finds are far more likely to still be available.
