About this route
London (LHR) to Sydney (SYD) is one of the long-haul trunk routes behind our notable flights, flown daily by competing carriers. Flown by QF2. It links London Heathrow Airport in United Kingdom with Sydney Kingsford Smith International Airport in Australia. The great-circle distance is about 9,190 nautical miles (10,578 statute miles), so expect roughly 20.5 hours in the air nonstop.
Every night we ask our fare provider for the cheapest one-way economy and business class fare other travellers recently found on this route and record it. A fare is flagged as a deal when it falls at least 30% below the route's 90-day typical price. Prices are a research starting point, not live availability — the booking links open the itinerary so you can confirm what's on sale right now.
Fares are approximate, from public sources, and can be stale — always verify before booking.
