San Francisco to Nairobi Flights (SFO to NBO): Connections, Flight Time and Arrival Guide

A one-stop trip, with plenty of places to make the stop

No airline flies nonstop from San Francisco to Nairobi. The distance is close to 9,600 miles, which rules it out for now, so every SFO to NBO itinerary connects at least once. The good news is that Nairobi is well served from the hubs that San Francisco already flies to nonstop.

The Gulf carriers are the most common choice. Qatar Airways connects through Doha and Emirates through Dubai, both with nonstops from San Francisco and onward flights to Nairobi. Turkish Airlines does the same through Istanbul. These routings tend to have the smoothest same-airline connections and generous checked-bag allowances.

The European routings are KLM through Amsterdam and Air France through Paris, both of which fly Nairobi daily as of recent schedules, and British Airways through London Heathrow. Lufthansa also serves Nairobi from Frankfurt, which connects with its San Francisco nonstop. KLM and Air France are partners of Kenya Airways and Delta in SkyTeam, so a mixed itinerary is often sold as a single ticket.

The only US-based option is Kenya Airways' nonstop from New York JFK, which you reach with a domestic flight from San Francisco on Delta, JetBlue, United or Alaska. It is the shortest routing in flying hours but needs a self-connection at JFK unless it is ticketed with Delta.

Flight time and distance

The great-circle distance between San Francisco and Nairobi is roughly 9,600 miles (about 15,400 km). Flying hours across the two legs total about 20 to 21 via the Gulf and 18 to 19 via Europe. Door to door, a realistic itinerary runs 22 to 28 hours depending on the connection. There is no quick way to do this trip.

Westbound is similar in the air. The time change works against you on the return, so most itineraries leave Nairobi late in the evening and reach San Francisco in the afternoon or evening of the following calendar day, with a connection in between.

Leaving from SFO

San Francisco International has three domestic terminals and one International Terminal split into boarding areas A and G. Qatar, Emirates, Turkish, KLM, Air France and British Airways depart from the International Terminal; which boarding area depends on the airline, so check the departures board. United's international flights also use boarding area G, and Delta and JetBlue to JFK leave from the domestic terminals.

The AirTrain loops all terminals, the garages and the BART station. BART reaches downtown San Francisco in about 30 minutes and is the easiest way to the airport without a car. For an afternoon or evening long-haul departure, three hours before the flight is reasonable; the International Terminal security lines peak in the mid-afternoon when the Asia and Gulf flights leave together.

Arriving at Jomo Kenyatta and getting into Nairobi

Jomo Kenyatta International has several terminal buildings. Terminal 1A handles Kenya Airways and its SkyTeam partners including KLM and Air France; other international carriers use adjacent sections of Terminal 1. The terminals are close together and linked by walkways and shuttle buses. Immigration uses the electronic travel authorisation you obtain before departure, and queues move reasonably in the early morning when most European and Gulf flights arrive.

The airport is about 15 km from the city centre along Mombasa Road. Pre-booked hotel transfers, airport taxis and ride-hail apps are all common; the expressway has cut the journey to 30 to 45 minutes outside rush hour, but it can be well over an hour at peak times. There is no rail link that is practical for arriving travellers. If you are heading straight to a safari, many lodges and operators arrange pickups, and the domestic airport for small-aircraft flights, Wilson, is on the other side of the city.

When to fly and when to book

Kenya's dry seasons are January to March and June to October, and the wildebeest migration in the Maasai Mara runs roughly July to October. Those months carry the strongest demand from the US and Europe, with July, August and the Christmas holidays the hardest to book. The long rains fall from late March through May and the short rains in November; lodges are quieter and more flexible then, and Nairobi itself is pleasant at any time of year because of its altitude.

For peak safari months, booking four to six months ahead is realistic, since lodge space and flights fill in step. Outside those months, two to three months ahead gives a good choice of connections.

Entry requirements and documents

As of recent rules, Kenya requires most visitors, including US passport holders, to obtain an electronic travel authorisation online before departure; it replaced the previous visa-on-arrival system. Apply through the official Kenyan government site only, since copycat sites charge extra. Your passport should have at least six months' validity and blank pages.

A yellow fever certificate is not normally required when arriving directly from the United States, but it can be if you transit through certain countries, and other vaccinations and malaria precautions are worth discussing with a travel clinic several weeks before you fly.

Time zones and jet lag

Nairobi is on East Africa Time, UTC+3, with no daylight saving. That makes it 10 hours ahead of San Francisco in summer and 11 hours ahead in winter. Eastbound you arrive in the early morning after two overnight legs; a short rest and then daylight is the best way to reset. Westbound you land in the afternoon or evening and the adjustment is usually easier, though the 24-hour journey leaves most people tired for a couple of days.

What travellers on this route get wrong

The first mistake is leaving the Kenyan travel authorisation to the last minute or buying it from an unofficial site. The second is a self-connection at JFK to Kenya Airways with too little margin; a late inbound from San Francisco means an overnight in New York. The third is landing in Nairobi and then trying to reach Wilson Airport for a safari flight within an hour, which city traffic can defeat. Each is simple to fix when you plan the trip, and painful afterwards.
