Cached-fare history: across 7 months, Sep is the cheapest for LON → KUL. Best time to be there: May–Jul.
Fares bottom out in September around $438 and peak in April near $761 — a $323 spread across the 7 months we track. The cheapest itinerary we are tracking makes one stop and takes about 16 hours outbound, on a 14-night trip — ticketed under China Southern, which on a connecting fare need not operate every leg. At $438 for 10,546 km each way, that works out to about $21 per 1,000 km flown. That is well under the $44 that long-haul fares on this board typically run. Across the 20 departure cities we track at a similar distance from Kuala Lumpur, this fare ranks 2nd — 3% above the $424 from Istanbul. It is also the 2nd cheapest of the 33 routes of similar length we watch out of London.

What is the cheapest month to fly from London to Kuala Lumpur?
Across 7 months of cached-fare history, Sep comes out cheapest on this route. The best months to actually be in Kuala Lumpur are May–Jul — when those overlap, that's your window.
How far in advance should I book LON → Kuala Lumpur?
We do not publish a number for this, because we cannot measure it yet. Answering it honestly means watching the same departure date on this route over many weeks as it approaches, and that archive is still filling up — so any "book N days ahead" figure here would be borrowed from somewhere else rather than measured. What we can measure is which month is cheap: across 7 months of cached fares, Sep comes out lowest on this route. See /guides/what-moves-a-flight-price/ for what does move a fare.
Are there nonstop flights from London to Kuala Lumpur?
The current cheapest fares involve a connection, ticketed under China Southern. Nonstop options exist on many dates at higher prices — check the live search for your exact dates.
Are these prices guaranteed?
No — these are cached fares found on real searches (this one on September 1). Airlines reprice constantly, so the booking search re-checks the live price before you pay. Fresher finds are far more likely to still be available.
