Nairobi to Mahé

Flights Nairobi -> Mahé (NBO-SEZ) — USD Fares, Airlines, Frequency

4 scheduled departures a week link Nairobi (NBO) in Kenya with Mahé (SEZ) — one every 1.8 days on average — flown by 2 catalogued carriers at a scheduled block time near 3.5 hours.

Flight NBO -> SEZ is operated by Kenya Airways, Air Seychelles (~4 flights per week, ~3.5h block time). This is an intra-Africa + Gulf hub transit corridor. As a rough planning range (an editorial estimate, not an observed fare), economy runs about $500-1,500; the fare observation on this page shows what our weekly snapshot recorded and when. Intra-Africa and Gulf-hub transit fares move week-to-week; 4-8 weeks is the typical sweet spot.

Great-circle distance Nairobi–Mahé is about 2,098 km, computed from the stored coordinates of NBO (-1.32, 36.93) and SEZ (-4.67, 55.52). What the figure fixes is the sector profile — 2,098 km against a scheduled 3.5-hour block time — and the fuel-and-crew economics behind the fare floor. It does not fix a compensation amount. No fixed-tariff compensation scheme reaches NBO–SEZ. EU261 and UK261 do band by distance, but they only cover flights departing an EU/EEA or UK airport — plus arrivals there on a bloc-licensed carrier — and neither endpoint here is one, whoever operates the flight. The Montreal Convention 1999 is what applies, and it pays provable loss, not a tariff.

Airlines on this route

2 carriers operate NBO–SEZ: Kenya Airways (KQ) and Air Seychelles (HM). Our carrier table records checked-baggage baselines of 23 kg; Kenya Airways sits in SkyTeam, with no alliance recorded for HM. That mix decides three things — the fare floor, whether your bag is through-checked on a connection, and which delay regulation covers you.

One column is blank rather than negative. We have no alliance information on record for Air Seychelles, so this page says nothing about its alliance membership either way. The practical question a connection turns on is narrower anyway: whether the two airlines on your itinerary interline, and whether both sectors sit on one ticket. Both are answerable at the booking screen, and neither depends on an alliance badge.

USD fares — NBO-SEZ

$602 was the lowest one-way economy price the Travelpayouts feed returned in our weekly snapshot for NBO–SEZ on TC, for a 2026-10-29T23:40:00+03:00 departure. That is a single cached observation on this one corridor — not a low across the site’s fare cache, and not a live price — so read it as an observed floor for NBO–SEZ on that date.

As a rough planning range (an editorial estimate, not an observed fare), economy on NBO-SEZ runs about $500-1,500; the fare observation on this page shows what our weekly snapshot recorded and when. Cached fares from a weekly Travelpayouts snapshot appear in the panel below, with their observation date; fare-month seasonality follows.

Across the 7 departure months our cache holds a one-way low for, the cheapest reading on NBO–SEZ was $222 for a Aug 2026 departure and the dearest was $551 for Dec 2026 — a spread of $329 between the best and worst month in the same cache. Month-to-month movement of that size is normal on this corridor and is usually worth more than any single booking trick.

One thing our fare data cannot tell you: whether the quote includes a checked bag. The cache stores a price and a carrier, not a fare family. On NBO–SEZ that matters most where a low-cost carrier or a basic-economy bucket is in the mix, because the cheapest screen number and the cheapest all-in number are then two different itineraries. Compare after adding the bag you will actually carry.

NBO–SEZ fare history — 2026-W23 to 2026-W25

3 weekly readings between 2026-W23 and 2026-W25 put the cached NBO–SEZ low between $559 and $849 — a $290 spread, 52% of the cheapest reading. The low landed in 2026-W24; the last reading in this table, 2026-W25, was $751. Each row is one weekly snapshot of the cheapest published quote, not an average of everything sold that week.

The cached low fell 12% between the first and last reading, from $849 to $751. Read it with the sample size in front of you: 3 observations over a ten-week window is a signal about this corridor’s volatility, not a forecast. What it does establish is a defensible floor — you now know $559 was achievable on NBO–SEZ inside the window, so a quote well above $849 is worth a second search.

Each row is a single weekly snapshot of the cheapest published quote, taken on one day, not an average of everything sold that week. Two consequences follow. A one-week dip can be a single small fare bucket rather than a trend, and a gap between weeks means we did not sample, not that fares vanished.

Checked baggage and uplift on NBO–SEZ — and what is not covered

23 kg is the checked-baggage baseline our carrier table records for the 2 airlines on NBO–SEZ, with a recorded diaspora uplift of up to +10 kg on Air Seychelles. Baselines are economy figures and fare-family dependent. The allowance printed on your issued ticket overrides any table, this one included.

A baggage baseline is the economy checked allowance an airline advertises as standard. It is not what your ticket necessarily grants. The same airline sells fare families below the baseline — hand-baggage-only and basic-economy buckets are exactly the ones that surface as the cheapest NBO–SEZ quote in any fare cache, including ours. The allowance printed on your itinerary overrides any table, ours included.

Where our table records a migrant or diaspora uplift — +5 kg on Kenya Airways and +10 kg on Air Seychelles — three exclusions usually bite. The uplift attaches to nominated corridors rather than the whole network; it rarely survives onto a codeshare or interline segment operated and ticketed by a different airline; and the deepest-discount fare buckets are commonly carved out. None of that makes the uplift fictional, but it does mean it has to be confirmed against your booking class, in writing, before you pack to it.

Search live fares

4 weekly departures across 2 carriers mean a live NBO–SEZ search returns several price points for the same day; our cached floor for the corridor is $602. Scheduled nonstop block time is 3.5 hours, so any result far above that is connecting whatever the screen says.

Comparing NBO–SEZ quotes fairly takes three corrections. Passenger count and cabin have to match across the tabs you are comparing. Elapsed time has to be read beside the price, since a connection can add most of a day to the 3.5-hour nonstop. And the baggage line has to be checked, because the cheapest fare family is usually the one carrying the least.

If anything about your NBO–SEZ trip can move, make it the dates. The gap between the cheapest and dearest departure month in our own fare log is routinely larger than any difference between one booking site and another. Fixed dates put you in competition with everyone else holding the same date, and the answer there is to book early rather than to keep looking.

About Mahé

3 catalogued corridors in this site’s data reach Mahé (SEZ), Seychelles International, ICAO FSIA, from 3 catalogued origins and 4 carriers in total. That count is this site’s coverage of Mahé, 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.

Mahé, Seychelles — destination on the intra-Africa + Gulf hub transit corridor. Destination currency: USD (we quote in USD throughout this guide).

Beyond NBO, our catalogue reaches Mahé from 2 other origins: Johannesburg (JNB) and Port Louis (MRU). That matters when the NBO–SEZ 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.
