Fares bottom out in November around $876 and peak in October near $1,174, 34% dearer, across the 4 months we track. The cheapest itinerary we are tracking makes 2 stops and takes about 11.5 hours outbound, on a 13-night trip — ticketed under Thai Vietjet Air, which on a connecting fare need not operate every leg. At $876 for 7,118 km each way, that works out to about $62 per 1,000 km flown. That is above the $44 per 1,000 km typical of long-haul fares here. Across the 26 departure cities we track at a similar distance from Zanzibar, this fare ranks 17th — 57% above the $557 from Istanbul. For context, the middle fare among the 24 routes of similar length we watch out of Bangkok is $676. The best time to be in Zanzibar: Jun–Oct.

Route facts
Good to know
Only slightly. The seasonal median is around $970 round-trip and this fare is 10% 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.
Across 4 months of cached-fare history, Nov comes out cheapest on this route. The best months to actually be in Zanzibar are Jun–Oct — when those overlap, that's your window.
We do not publish a number for this, because we cannot measure it yet.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, Nov comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.
The current cheapest fares involve a connection, ticketed under Thai Vietjet 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.
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.
