When this route gets cheap.
The cheapest itinerary we are tracking makes one stop and takes about 16 hours outbound, on a 20-night trip — ticketed under Lufthansa, which on a connecting fare need not operate every leg. At $1,609 for 11,564 km each way, that works out to about $70 per 1,000 km flown. That is above the $42 per 1,000 km typical of ultra-long-haul fares here. Across the 15 departure cities we track at a similar distance from Nairobi, this fare ranks 14th — 2.7× the $593 we hold from Houston. For context, the middle fare among the 26 routes of similar length we watch out of Boston is $1,090. We have 1 month of cached prices for this route so far — not enough to call a fare cheap or expensive, so we publish the price without a percentage. Fare history here is still too short to name a cheap season. The best time to be in Nairobi: Jun–Oct · Jan–Feb.

The median cached fare across this calendar is 142% higher than when tracking began on 9 Aug — $664 then versus $1,609 now, across 10 recorded snapshots. This is a calendar-level trend, so an individual deal above can be lower. The lowest single day we have seen here is $500, on 2 Dec.
These are the only days we have a cached price for on this route so far — not the only days it flies. The search above covers any date.

Good to know
BOS → NBO, answered.
How far in advance should I book BOS → Nairobi?
We do not publish a number for this, because we cannot measure it yet.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. Our guide Why flight prices change covers the levers we can measure.
Are there nonstop flights from Boston to Nairobi?
The current cheapest fares involve a connection, ticketed under Lufthansa. 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 15 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.
