The great-circle distance is about 2,499 nautical miles (2,876 statute miles), so expect roughly 6 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.
Fares are approximate, from public sources, and can be stale — always verify before booking.
