This guide covers who flies the route, what a fair return fare looks like in pounds, and when to book for the best price.

Fares from London to Hong Kong (GBP)
Hong Kong is a year-round city destination, so fares are driven more by holidays and school breaks than by weather. Christmas and New Year, Chinese New Year (late January or February) and the July–August summer holidays are the peaks; late spring and autumn are the value windows. The table below shows when the route is busiest. We no longer print per-month fare estimates here, because they were never measured.
| Month | Typical return (economy) | Demand |
|---|---|---|
| January | — | high (Chinese New Year) |
| February | — | high |
| March | — | medium |
| April | — | medium |
| May | — | low-medium |
| June | — | low-medium |
| July | — | high (summer holidays) |
| August | — | high |
| September | — | low-medium |
| October | — | medium |
| November | — | medium |
| December | — | very high (holidays) |
We do not quote a target fare for this route. Our price tracking holds no recorded observations for it, so a “typical” or “good deal” figure here would be an estimate dressed up as a measurement — so this page leaves it out rather than guess. The seasonal pattern above is the part we can stand behind; check the live fare for the number.
Airlines on this route
Non-stop (about 12 hours):
- Cathay Pacific — non-stop Heathrow → Hong Kong, the flag carrier with multiple daily flights and a consistently strong economy and premium product.
- British Airways — non-stop from Heathrow Terminal 5, daily on the Boeing 777 or Airbus A350.
One-stop (usually the cheapest, about 15–18 hours total):
- Qatar Airways via Doha — frequent, strong economy, often the best all-round value.
- Emirates via Dubai — regular connections from Heathrow and Gatwick.
- Turkish Airlines via Istanbul — wide schedule and often competitively priced.
- Singapore Airlines via Singapore — excellent product with a short onward hop to Hong Kong.
Because the one-stop carriers compete hard, they usually undercut the non-stops by £80–£200. If time matters more than money, book Cathay Pacific or British Airways non-stop; if price is the priority, a single stop through Doha, Dubai or Istanbul is the sweet spot.
When to book & how to save
- Book 2–4 months ahead for the best balance of price and choice; long-haul fares to Hong Kong rarely get cheaper in the last few weeks.
- Avoid the peaks if you can: Christmas/New Year, Chinese New Year and the July–August summer holidays are the most expensive and busiest.
- Target spring and autumn (roughly April–June and September–November) for the lowest fares and the most comfortable weather.
- Weigh the non-stop premium: the direct flights save you 3–6 hours over a connection — worth it if your time is tight, less so if you are chasing the lowest price.
- Check checked-bag rules: full-service and Gulf carriers usually include 25–30 kg to Hong Kong; the cheapest “light” fares may not, so compare the all-in price.
Arriving in Hong Kong
All flights land at Hong Kong International (HKG) on Chek Lap Kok, about 34 km west of the city. The fastest way in is the Airport Express train to Kowloon and Hong Kong Island (around 24 minutes, roughly £10–£12), which also offers free in-town check-in and shuttle buses to major hotels. A metered taxi to Kowloon or Central costs around £30–£40 including the bridge tolls, and airport buses (the “A” routes) are a cheap alternative if you are travelling light.
