Fares from Brussels to Hong Kong (EUR)
Hong Kong is a year-round destination, but fares climb over the European summer holidays, the Christmas and New Year peak, and Chinese New Year (late January or February). Spring and autumn shoulder months are the best value. The figures below are typical economy return fares in euros; the Cathay non-stop tends to sit toward the higher end, with the cheapest fares coming from one-stop Gulf carriers.

| January | €600 – €850 | medium-high (CNY some years) |
| February | €640 – €900 | high (Chinese New Year) |
| March | €560 – €780 | medium |
| April | €560 – €780 | medium |
| May | €540 – €740 | low-medium |
| June | €600 – €840 | medium (summer) |

Reference points from our own deal tracking: a strong one-stop fare lands around €430–€500 return, a typical fair price is roughly €560, and anything under about €520 is worth booking quickly. Fares that include a checked bag usually start around €500–€640, and the Cathay non-stop generally sits toward the top of the range outside the quiet weeks.
Airlines on this route
Non-stop (about 11½ hours):
- Cathay Pacific — non-stop Brussels → Hong Kong, roughly four times a week; Hong Kong’s flag carrier, with Economy, Premium Economy and Business cabins and a consistently well-rated hard product.
One-stop (usually the cheapest, about 15–18 hours total):
- Qatar Airways via Doha — frequent, strong economy, often the best-value one-stop.
- Emirates via Dubai — reliable widebody comfort and good Brussels connections.
- Etihad via Abu Dhabi — competitive fares with a single change.
- Turkish Airlines via Istanbul — typically among the lowest headline fares.
Because the one-stop carriers compete hard, they usually undercut the Cathay non-stop by €80–€200. If time matters more than money, book the direct flight; if price is the priority, a single stop through Doha, Dubai, Abu Dhabi 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, the July–August summer holidays and Chinese New Year are the priciest and busiest.
- Fly in the shoulder months (May, September, October) for the lowest fares and pleasant, drier weather.
- Weigh non-stop against one-stop — a Gulf connection can save real money, but Cathay’s direct flight saves several hours each way.
- Check checked-bag rules: full-service and Gulf carriers usually include 25–30 kg to Hong Kong; the lowest “light” fares may not, so compare the all-in price.
Arriving in Hong Kong
All flights land at Hong Kong International (HKG) on Lantau Island, about 34 km west of Central. The fastest way in is the Airport Express train, which reaches Kowloon in about 22 minutes and Hong Kong Station in 24 (roughly €12, less with an Octopus card or a group ticket). A metered taxi to Central costs around €35–€45 including tolls, and frequent Cityflyer airport buses serve the main districts for a few euros.
