Booking a flight to Kenya sits at the intersection of two systems that don't always talk to each other: the airline industry, which cares only about getting you to Jomo Kenyatta International Airport, and the Kenyan government's entry requirements, which have changed more than once in the last three years. This article covers both – the practical business of finding and pricing a seat, and the paperwork you need before you board. We update it on a quarterly cycle because fares shift with the seasons and Kenya's entry rules have proved genuinely unstable since 2023.

Quick answer

Most travellers reach Kenya by flying into Jomo Kenyatta International Airport (JKIA) in Nairobi, on either a nonstop service (Kenya Airways from New York JFK, or Kenya Airways and British Airways from London Heathrow) or a one-stop itinerary via a European or Gulf hub. As of 2026-01, entry requires an Electronic Travel Authorization (eTA) applied for online before departure, a passport valid well beyond your travel dates, and – for travellers arriving from a yellow fever risk country – proof of vaccination. Return economy fares from the US or UK typically run into four figures; premium cabins considerably more. Book your eTA and your seat separately, and do both with time to spare.

What you need

Before you look seriously at fares, gather four things.

A valid passport. Kenya's own guidance, echoed by the airlines that fly there, asks for a passport valid for a period well beyond your planned departure date from Kenya – in practice, most carriers and immigration desks will not let you board with fewer than six months' validity remaining. Passports nearing that threshold cause more denied boardings than almost any other single issue; check the expiry date now, not the week before you fly.

An Electronic Travel Authorization. Kenya moved away from its earlier eVisa system in 2024, replacing it with an eTA that almost all foreign nationals must obtain online before travel, regardless of any earlier announcements about visa-free entry. The application is made through Kenya's official government portal – never through a third-party site that charges a "service fee" on top, a scam that has caught out plenty of first-time visitors. Have a digital passport photo, your passport bio page, and your itinerary details ready before you start the form.

Proof of onward travel and accommodation. Immigration officers can ask for evidence of where you're staying and how you intend to leave the country. A confirmed safari itinerary, a hotel booking, or a return flight all suffice. Few travellers are actually asked, but arriving without any of it is a needless risk.

A yellow fever certificate, conditionally. Kenya requires proof of yellowfever vaccination only from travellers arriving from, or having transited through, a country the World Health Organization classifies as having risk of yellow fever transmission – this includes much of West and Central Africa and parts of South America. If your journey starts in the US, UK or Australia and routes through Europe or the Gulf, you will not normally need it. If your itinerary includes a stopover in a risk country, carry the certificate: officers do check, and the vaccination must have been given at least ten days before arrival to count. The CDC and the NHS both publish current risk-country lists, and we'd recommend checking whichever applies to you rather than relying on secondhand advice, since the list is reviewed periodically.

Step-by-step

  1. Check your passport's expiry date first. If it falls short of six months' validity beyond your Kenya departure date, renew it before doing anything else – airline check-in staff will refuse boarding over this, and it's the single most common reason for a ruined trip that had nothing to do with the airline or the weather.
  1. Apply for your eTA through Kenya's official portal. Do this at least a few weeks before departure, though the processing time is often quoted as a matter of days. Save the confirmation as a PDF and keep a printed copy in your hand luggage; airport wifi has a habit of failing exactly when you need to show an email.
  1. Search flights with flexible date tools before committing. Fares to Nairobi vary considerably by day of week and by season, and the flexible-date calendars on most airline and aggregator sites will show you the swing at a glance. Kenya's high season, roughly from June through October and again around the December holidays, commands noticeably higher fares than the shoulder months.
  1. Decide between a nonstop and a one-stop routing. From New York, Kenya Airways operates the only nonstop service to Nairobi; travellers from other US cities will connect, typically through Amsterdam, Paris, London or a Gulf hub such as Doha or Dubai. From the UK, both British Airways and Kenya Airways fly nonstop from Heathrow. Weigh the extra hours of a connection against the fare saving – it is often substantial.
  1. Book directly with the airline or a reputable agent, not a discount aggregator with no phone support. Kenya-bound itineraries sometimes involve a codeshare between two carriers, and if a schedule changes, you want someone reachable who can rebook you without a lost afternoon on hold.
  1. Arrange your yellow fever certificate, if your routing requires one, well before departure, since the ten-day rule after vaccination is non-negotiable and cannot be resolved at the airport.
  1. Reconfirm your safari or lodge bookings and have the confirmation documents accessible on arrival, in case immigration asks for proof of onward plans.
  1. On arrival at Jomo Kenyatta International Airport, follow signage to the immigration hall and have your eTA printout, passport and any required health documents ready together, rather than searching for them at the desk.

Costs and timing

We're deliberately cautious about quoting exact figures here, because both airfares and government fees move, and a number printed in January can be wrong by April. That said, here is what to expect and where to verify it.

Airfare. A round-trip economy fare between the US East Coast and Nairobi has, in recent years, typically landed somewhere in the four-figure range in US dollars during shoulder season, rising well beyond that at the height of the safari season or around Christmas. From the UK, Heathrow–Nairobi round trips have generally been somewhat cheaper given the shorter distance and greater competition on the route. West Coast US departures cost more than East Coast ones simply because of the extra connecting leg. These are patterns, not promises – always check a live fare search for your actual dates. Our cheap flights to Kenya guide goes into more depth on route-by-route pricing strategy, and if you're weighing a lie-flat seat for the long sectors, our business class flights to Kenya article covers when the upgrade is worth it.

eTA fee. The Kenyan government charges a processing fee for the eTA, payable online at the time of application. Fees have changed at least once since the system's introduction, so treat any number you read (including, eventually, this one) as provisional and confirm the current figure on the official portal before you pay.

Processing time. The eTA is generally processed within a short number of business days, though the portal itself will give you a specific estimate at the time of application. Apply earlier than you think you need to; a backlog at any government system is not something a traveller can negotiate around at the last minute.

Validity. Once issued, an eTA is generally valid for a limited entry window, and a separate visitor permit is typically granted for a set stay period on arrival, which can sometimes be extended through Kenyan immigration if your trip runs long. Confirm current validity periods on the official portal, since these details have been the ones most subject to revision.

Edge cases

Children travelling with one parent or with grandparents. Kenyan immigration has, at various points, asked for consent documentation when a child travels without both parents present. Requirements shift, and enforcement has been inconsistent by account of many travellers, but the safe approach is to carry notarised consent from the absent parent (or both parents, if the child travels with a third party) along with the child's own passport and eTA. Don't rely on this not being checked.

Multiple entries. If your itinerary includes a side trip to Tanzania, Uganda or Zanzibar and a return to Kenya, check whether your eTA is single-entry or covers multiple entries within its validity window. Many safari circuits cross borders more than once, and assuming your first entry document covers a return leg has caught out travellers doing a Serengeti–Maasai Mara combination.

Transit passengers. If you are only transiting through Nairobi's airport without clearing immigration, requirements differ from those for travellers entering the country. Rules on this have been revised before, so check the current transit policy on the official portal rather than assuming a layover is automatically exempt.

Expired or soon-to-expire passports. As covered above, this is the most common and most avoidable failure point. There is no waiver process at the check-in desk; airlines are contractually obliged to enforce the destination country's entry rules and will deny boarding rather than risk a fine for carrying an inadmissible passenger.

Dual nationality. Travellers holding Kenyan citizenship alongside another nationality should check whether they are expected to enter and exit Kenya on their Kenyan passport rather than their other one. This is a common source of confusion for diaspora travellers visiting family, and the rule has practical consequences for which document you present at check-in.

Late applications. If you are booking and travelling within a matter of days, apply for the eTA the moment your flight is confirmed, not after you've packed. Expedited or emergency processing is not something to count on, and a delayed application is one of the few problems on this list that genuinely cannot be fixed by throwing money at it on the day.

Common mistakes

Most of the errors we see aren't exotic; they're simple oversights that a careful traveller like Helen wouldn't expect to trip her up.

  • Paying a third-party website a mark-up to "process" an eTA that the official portal issues directly, at a lower cost, without an intermediary.
  • Assuming the old eVisa rules still apply, because that's what a five-year-old blog post says.
  • Booking a passport with less than six months' validity and discovering the problem at the check-in counter, not before.
  • Overlooking that a Kenya–Tanzania–Kenya safari circuit needs the entry document to cover the return leg.
  • Forgetting that a yellow fever certificate, if required by your routing, needs ten clear days after vaccination to be valid – not ten days including the day of the jab.
  • Not carrying a printed copy of the eTA approval when airport wifi is unreliable.
  • Confusing baggage allowances between the international sector and any connecting flight run by a partner or regional carrier, which can have a noticeably lower limit.

FAQ

How much is a flight to Kenya?

A round-trip economy flight to Kenya from the US typically costs a figure in the low-to-mid four digits in US dollars, though this depends heavily on departure city, season and how far in advance you book. From the UK, fares are generally somewhat lower given the shorter routing. Always check a live fare search for your specific dates rather than relying on a fixed number, since Kenya's high season (roughly June to October, plus the December holidays) commands a noticeable premium over shoulder-season pricing.

How much does it cost to fly to Kenya from the US?

Flying to Kenya from the US costs more from West Coast departure cities than from the East Coast, because West Coast itineraries almost always require an additional connecting flight. New York offers the only nonstop option, via Kenya Airways; other US cities connect through a European or Gulf hub, which adds both time and, often, cost. Checking a flexible-date fare calendar before committing to specific days can reveal meaningful savings.

Do I need a visa to fly to Kenya?

Travellers to Kenya do not apply for a traditional visa; as of 2026-01, nearly all foreign nationals instead apply online for an Electronic Travel Authorization (eTA) before departure. This replaced Kenya's earlier eVisa system, and the application is made directly through the government's official portal. Apply well before your trip, since processing, though generally quick, is not instantaneous.

What documents do I need to fly to Kenya?

Flying to Kenya requires a passport valid well beyond your travel dates (in practice, at least six months' remaining validity is the safe threshold most airlines enforce), an approved eTA obtained in advance online, and, for travellers arriving from or transiting through a yellow fever risk country, a valid vaccination certificate. Evidence of onward travel or accommodation is sometimes requested at immigration, so it's worth having a printed or downloaded itinerary to hand.

Is there a nonstop flight from the US to Kenya?

Kenya Airways operates the only nonstop flight between the US and Nairobi, departing from New York's JFK airport. Travellers from any other US city will need to connect, most commonly through a European hub such as Amsterdam, Paris or London, or through a Gulf hub such as Doha or Dubai.

How long is the flight to Kenya?

A nonstop flight between New York and Nairobi runs a long-haul duration typically in the mid-teens of hours; a one-stop itinerary from elsewhere in the US or from the UK adds the connecting flight time and any layover on top of that. From London, the nonstop sector itself is somewhat shorter, given the shorter overall distance.

Can I use my eTA for multiple entries into Kenya?

Whether an eTA covers multiple entries depends on the terms issued at the time of approval, and this is worth checking carefully if your trip includes a border crossing into Tanzania or Uganda and a return to Kenya. Confirm the entry terms on the official eTA portal before finalising a multi-country safari itinerary, since assuming single-entry coverage extends to a return leg is a common and avoidable error.

A last word on planning ahead

None of this paperwork is difficult in isolation; what catches travellers out is sequencing. Helen's instinct, and a sound one, is to book the flight first because it feels like the biggest decision. In practice, the passport check and the eTA application belong at the very start of the process, before a single fare is compared, because they're the only two things on this list that can actually stop a confirmed, paid-for trip at the departure gate. Everything else – choosing a routing, weighing a nonstop against a one-stop saving, deciding whether the extra cost of a premium cabin is worth it over a long sector – is a matter of preference, not permission. Get the permission sorted first, and the rest of the planning, including the wider question of when in the year to travel, becomes a much more enjoyable problem to solve. Our guide to the best time to travel to Kenya is a natural next stop once your entry paperwork is settled, and if currency and budgeting are next on your list, currency in Kenya and our notes on the cost of living in Kenya are worth reading before you finalise how much cash to carry.
