As of early 2026, the cost of a one-way economy class flight from Kenya (usually Nairobi Jomo Kenyatta International Airport) to the United Kingdom (typically London Heathrow or London Gatwick) varies significantly based on when you book and which airline you choose. For a non-stop flight with Kenya Airways or British Airways, prices generally range between $850 and $1,200 (roughly 110,000 to 155,000 KES) if booked at least a month in advance. If you choose an indirect flight with a layover in a hub like Dubai (Emirates), Doha (Qatar Airways), or Addis Ababa (Ethiopian Airlines), you can often find cheaper fares ranging from $600 to $850. Prices can spike considerably during peak travel seasons, such as the Christmas holidays and August, when they may exceed $1,500. It is also important to factor in additional costs like the UK Visa application fee (roughly $150 for a standard 6-month visitor visa) and the new UK Electronic Travel Authorisation (ETA) fee of £10 for eligible travelers, which must be secured before boarding.
