About this route
Hong Kong (HKG) to London (LHR) is one of the long-haul trunk routes behind our notable flights, flown daily by competing carriers. Flown by CX1. It links Hong Kong International Airport in Hong Kong with London Heathrow Airport in United Kingdom. The great-circle distance is about 5,200 nautical miles (5,985 statute miles), so expect roughly 12 hours in the air nonstop.
Every night we ask our fare provider for the cheapest one-way economy fare other travellers recently found on this route and record it, with the airline and the seller it was found with. 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. business class fares aren't priced by our provider, so that section links to live searches instead.
Fares are approximate, from public sources, and can be stale — always verify before booking.
