Fare seasonality

When this route gets cheap.

Fares bottom out in February around $647 and peak in July near $1,064, 64% dearer, across the 11 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 $647 for 9,559 km each way, that works out to about $34 per 1,000 km flown. That is below the $44 per 1,000 km typical of long-haul fares here. Across the 33 departure cities we track at a similar distance from Tokyo, this fare ranks 11th — 11% above the $584 from Dubai. That puts it in the cheaper half of the 36 routes of similar length we watch out of London, where the middle fare is $647. The best time to be in Tokyo: Mar–May · Oct–Nov.

Good to know

LON → TYO, answered.

Is $647 a good price for London to Tokyo?

Only slightly. The seasonal median is around $735 round-trip and this fare is 12% 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 Tokyo?

Across 11 months of cached-fare history, Feb comes out cheapest on this route. The best months to actually be in Tokyo are Mar–May · Oct–Nov — when those overlap, that's your window.

How far in advance should I book LON → Tokyo?

We do not publish a number for this, because we cannot measure it yet.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 11 months of cached fares, Feb 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 Tokyo?

The current cheapest fares involve a connection, ticketed under China Southern. 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.
