Flights Nairobi -> Washington (NBO-IAD) — USD Fares, Airlines, Frequency
3 scheduled departures a week link Nairobi (NBO) in Kenya with Washington (IAD) — one every 2.3 days on average — flown by 1 catalogued carrier at a scheduled block time near 15.0 hours.
Nairobi to Washington connects Kenya with the United States capital, with around 3 flights a week. The route carries members of the Kenyan community in the US visiting family, business travellers, students and connecting passengers. Block time is around fifteen hours, a major long-haul sector.
Great-circle distance Nairobi–Washington is about 12,187 km, computed from the stored coordinates of NBO (-1.32, 36.93) and IAD (38.95, -77.46). What the figure fixes is the sector profile — 12,187 km against a scheduled 15.0-hour block time — and the fuel-and-crew economics behind the fare floor. It does not fix a compensation amount. The corridor touches the United States, where DOT rules cover refunds rather than delay compensation: a cancellation or a significant schedule change you decline is refunded automatically, while a long delay that still operates carries no statutory cash payout at all.
Airlines on this route
1 carrier operates NBO–IAD: Kenya Airways (KQ), a full-service airline based in Kenya, a member of SkyTeam, with a 23 kg checked-baggage baseline in our table. We estimate about 3 weekly departures on the corridor, with a scheduled block time near 15.0 hours.
Kenya Airways operates NBO-IAD, flying a full-service widebody with a checked baggage allowance and meals included. Nairobi is the carrier’s main hub, so the route also carries passengers connecting from across East Africa onward to the US.
| Carrier | Baggage baseline | Alliance |
|---|---|---|
| Kenya Airways (KQ) | 23 kg | SkyTeam |
Our carrier table records a diaspora / migrant-worker baggage uplift of +5 kg on Kenya Airways. Read that as a carrier promotion, not a universal entitlement: uplifts of this kind are normally tied to specific fare families and specific corridors, they are rarely honoured on a codeshare or interline segment issued by another airline, and the cheapest promotional fare buckets are the ones most often excluded. Confirm the allowance against your own booking class before you pack to it.
USD fares — NBO-IAD
$798 was the 2026-W29 reading in our weekly fare log for NBO–IAD, across 2 readings that range $649 to $798.
NBO-IAD fares move with the family calendar — the December holidays and the summer are the busiest and most expensive. For those dates, booking three to five months ahead is sensible. Outside the peaks, eight to twelve weeks usually secures a workable economy fare in USD.
Book 3-5 months ahead. Fares climb steeply around the December holidays and the summer, when diaspora travel peaks. That window is general guidance rather than a rule for this single pairing; on a corridor with 3 weekly departures, the practical constraint is often seat availability on the days you can actually travel, not the headline fare.
Treat every cached figure on NBO–IAD as a fare, not as a trip cost. What the cache cannot see is the booking class behind the number: checked baggage, seat selection and change rights are all fare-family attributes, and the buckets that produce record-low quotes are the ones that include least. Price the trip you are actually taking.
If your NBO–IAD flight is cancelled: which rules apply
0 dollars of fixed delay compensation are due on NBO–IAD, the corridor’s United States endpoint notwithstanding. US DOT rules cover refunds, not compensation: a cancellation or a significant schedule change you decline triggers an automatic refund, but a long delay carries no statutory payout.
| Regime | When it applies | Remedy for a long delay / cancellation |
|---|---|---|
| US DOT | Flights to or from the United States. | No cash compensation for delays; an automatic refund is due for cancellations and significant schedule changes you decline (US DOT 2024 rule). |
| Montreal Convention 1999 | Any international itinerary — baggage and delay losses. | Compensation for lost, damaged or delayed baggage (up to 1,519 SDR per passenger) and for provable losses caused by delay (up to 6,303 SDR), limits in force since 28 December 2024. |
What does not apply matters as much as what does, because claim-management services will happily open a file either way. On NBO–IAD: EU261 does not reach this corridor at all — neither endpoint is an EU/EEA airport, and carrier nationality alone never triggers it and UK261 does not apply, since no leg touches a UK airport. Filing under a scheme that does not cover your itinerary costs weeks and gets a rejection, so match the regulation to the departure airport and the operating carrier before you start.
Do you need a visa to fly NBO–IAD?
Entry rule for United States, by passport: B1/B2 visitor visa unless your passport is from a Visa Waiver Program country. Fee $185 USD non-refundable application (MRV) fee for a B visitor visa; maximum stay Decided by the officer at the port of entry. That row names the passports it covers; for any other passport, check the linked government portal before booking.
| Entry type | Fee | Maximum stay | Official source |
|---|---|---|---|
| B1/B2 visitor visa unless your passport is from a Visa Waiver Program country | $185 USD non-refundable application (MRV) fee for a B visitor visa | Decided by the officer at the port of entry | United States official source |
Worth knowing before you book: Fee from the official US visa appointment service for South Africa. In-person interview at a US embassy or consulate.
The trap on NBO–IAD is not usually the destination visa — it is the transit. A connection can put you airside in a third country that requires a transit visa for your nationality even though you never leave the terminal, and airlines deny boarding at origin when documentation for the whole itinerary is not in order. Check every country your ticket touches, not just United States, and check it against your own passport rather than a fellow traveller’s.
Search live fares
3 weekly departures across 1 carrier mean a live NBO–IAD search returns several price points for the same day; our weekly fare log has recorded readings as low as $798 (see the dated history on this page). Scheduled nonstop block time is 15.0 hours, so any result far above that is connecting whatever the screen says.
Search NBO -> IAD on Aviasales ->
A live NBO–IAD search is only comparable once three things are pinned: the cabin and passenger count, so totals are like for like; the elapsed time, which separates a genuine nonstop from a routing that merely costs the same; and the baggage the fare includes. Skip any of the three and you are comparing two different products.
Flexible dates are the highest-leverage setting on this corridor. Our own cache shows month-to-month movement on NBO–IAD that dwarfs the difference between booking gates, so one search across a whole month tells you more than five searches on a single date. Where the dates cannot move — a pilgrimage window, a school term, a contract start — book earlier instead of searching harder.
About Washington
6 catalogued corridors in this site’s data reach Washington (IAD), Dulles International, ICAO KIAD, from 6 catalogued origins and 3 carriers in total. That count is this site’s coverage of Washington, not the airport’s published schedule. Each of those corridors has its own guide with carriers, weekly frequency, scheduled block time and whatever the fare cache holds.
Washington is the capital of the United States, a centre of government and international institutions, home to a substantial Kenyan community. For travellers from Nairobi it is a family-visit, business and institutional destination.
Beyond NBO, our catalogue reaches Washington from 5 other origins: Abuja (ABV), Accra (ACC), Addis Ababa (ADD), Johannesburg (JNB) and Lagos (LOS). That matters when the NBO–IAD fare is unattractive: on a continent where positioning flights are cheap, flying out of a different gateway is a real option, and each of those corridors has its own guide, carriers and cached fare floor on this site.
On the ground United States uses USD, while every fare on this site is quoted in USD. That split is deliberate: USD is the only currency that makes a Lagos fare and a Nairobi fare comparable on one page, but it means the card you pay with will convert twice if your bank settles in a third currency. Airline sites often offer payment in USD or in your home currency — the airline’s own rate is rarely the better of the two.

The corridor links are there to be used as alternatives, not as further reading. If the NBO–IAD fare or schedule does not work, a different African gateway to Washington is often the better fix — positioning within the continent is cheap relative to the long-haul sector, and the fare gap between two origins to the same destination is regularly wider than the positioning ticket. The catch is that separately issued sectors carry no protection if the first one runs late.
