Fares bottom out in November around $541 and peak in December near $860, 59% dearer, across the 6 months we track. The cheapest itinerary we are tracking makes one stop and takes about 13.5 hours outbound, on a 6-night trip — ticketed under Tianjin Airlines, which on a connecting fare need not operate every leg. At $541 for 8,958 km each way, that works out to about $30 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 27 departure cities we track at a similar distance from Beijing, this fare ranks 4th — 5% above the $516 from Vienna. That puts it in the cheaper half of the 19 routes of similar length we watch out of Sydney, where the middle fare is $668. The best time to be in Beijing: Sep–Oct · Apr–May.

Route facts
Good to know
Only slightly. The seasonal median is around $650 round-trip and this fare is 17% 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.
Across 6 months of cached-fare history, Nov comes out cheapest on this route. The best months to actually be in Beijing are Sep–Oct · Apr–May — when those overlap, that's your window.
We do not publish a number for this, because we cannot measure it yet.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 6 months of cached fares, Nov comes out lowest on this route. Our guide Why flight prices change covers what does move a fare.
The current cheapest fares involve a connection, ticketed under Tianjin Airlines. We hold no nonstop fare on this route right now, which does not mean none flies — search your exact dates to see what does.
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.
