Cheap flights from London to Kuala Lumpur

September is the cheapest month for this route, and the price calendar covers every month of the year, so you can shift your dates before you commit. Fares climb through the northern summer and again around the year-end holidays, when travel between Britain and Malaysia peaks in both directions. Midweek departures from London tend to undercut weekend ones, and Tuesday and Wednesday are usually the quietest days to leave. If your dates are fixed, book early; if they can move, September and the shoulder weeks around it are where the savings sit.

There are no direct flights from London to Kuala Lumpur, so every ticket means at least one connection. The carriers fall into two groups. Air Arabia and Ajet keep fares low by unbundling, so bags and seat selection often cost extra. Full-service names such as Singapore Airlines, Gulf Air, Air India, Air China, China Southern Airlines, Shenzhen Airlines, Hainan Airlines and Turkmenistan Airlines usually include a checked bag and meals. Where they differ most is the connection: Gulf Air and Air Arabia stop in the Gulf, the Chinese carriers route through mainland China, and Singapore Airlines goes via Singapore. Compare total journey time as well as the fare.

Kuala Lumpur International Airport is the only airport serving the Malaysian capital, and it sits well outside the city, so plan your onward leg before you land. The airport train is the quickest way in and runs to the main city rail station, buses are slower but drop passengers at several points in town, and taxis and ride-hailing cars work on meters or fixed fares depending on the counter you use. Buy your train ticket or book your car after you clear immigration rather than from anyone approaching you in the arrivals hall. If you land late at night, check that your onward transport still runs, and keep some local currency handy for the first leg.

Country facts: Wikidata

• Pick your London airport first: Heathrow, Gatwick, Stansted, Luton and London City serve different carriers and add different transfer costs.
• Check whether a checked bag is included, especially with Air Arabia and Ajet, where bags are usually sold separately.
• If your trip is split across two tickets, leave a long gap between flights; a missed connection is then on you.
• Confirm your passport is valid for the whole trip and check Malaysia's current entry rules before booking.
• Start with September in the price calendar, then compare the months either side if your dates can move.
• Compare total journey time, not just the fare, since some routings through China or the Gulf are far longer.
