Cheap flights from London to Hong Kong

When to fly: February is the cheapest month on this route, so if your dates flex, aim for late winter. Fares rise through the summer school holidays and again around Christmas and Chinese New Year, when Hong Kong fills with visiting families. Midweek departures from London are usually quieter and priced lower than Friday or Sunday flights, and Tuesday or Wednesday returns are usually quieter too. For spring and autumn travel, book a few months ahead; for February, you can often leave it later.

Airlines on this route: Indigo is the low-cost option in the mix, while China Eastern, China Southern, Air China, Hainan Airlines, Air India, Finnair, Etihad Airways, Qatar Airways and Royal Brunei are full-service carriers. None fly non-stop from London, so your itinerary is built around one or two connections, usually through the Gulf, mainland China, India or Helsinki. Full-service fares normally include a checked bag and meals, while Indigo prices extras separately, so compare the total rather than the headline fare. Long layovers are common on lower-priced combinations, so check total journey time as well as the ticket.

Arriving: every flight lands at Hong Kong International, the city's only airport, built on reclaimed land on Lantau Island. It sits well away from Kowloon and Hong Kong Island, so allow real time for the transfer into town. The Airport Express train runs straight to Central, with buses and taxis covering the same trip. If you are heading to Kowloon or the New Territories, a bus or taxi may drop you closer than the train. Late-night arrivals should check the last train and bus times before booking.

Country facts: Wikidata

• Check which London airport you leave from — Heathrow, Gatwick, Stansted, Luton and London City are not interchangeable.
• Confirm what your fare includes, since low-cost tickets charge separately for checked bags and seats.
• If you book two separate tickets, leave a long buffer for the connection — a missed leg is not protected.
• Check Hong Kong entry rules and passport validity before you pay.
• Compare the price calendar across the year, not one date — February sits well below summer.
• Factor in the transfer from Hong Kong International into town when you choose your arrival time.
