Fare seasonality

When this route gets cheap.

Fares bottom out in November around $497 and peak in March near $592, 19% dearer, across the 5 months we track. The cheapest itinerary we are tracking makes one stop and takes about 17.5 hours outbound, on a 28-night trip — ticketed under Air China, which on a connecting fare need not operate every leg. At $497 for 10,848 km each way, that works out to about $23 per 1,000 km flown. That is well under the $44 per 1,000 km that long-haul fares on this board typically run. Across the 20 departure cities we track at a similar distance from Singapore, this fare ranks 2nd — 5% above the $473 from Barcelona. That puts it in the cheaper half of the 31 routes of similar length we watch out of London, where the middle fare is $647. The best time to be in Singapore: Feb–Apr.

Good to know

LON → SIN, answered.

Is $497 a good price for London to Singapore?

Only slightly. The seasonal median is around $590 round-trip and this fare is 16% under it. We do not call a drop notable until 20%, so this is an ordinary price for the route rather than a reason to hurry.

What is the cheapest month to fly from London to Singapore?

Across 5 months of cached-fare history, Nov comes out cheapest on this route. The best months to actually be in Singapore are Feb–Apr — when those overlap, that's your window.

How far in advance should I book LON → Singapore?

We do not publish a number for this, because we cannot measure it yet.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 5 months of cached fares, Nov comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.

Are there nonstop flights from London to Singapore?

The current cheapest fares involve a connection, ticketed under Air China. We hold no nonstop fare on this route right now, which does not mean none flies — search your exact dates to see what does.

Are these prices guaranteed?

No — these are cached fares found on real searches (this one on 17 October). 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.
