Your guide to booking Sydney to Hong Kong flights

Get tips on when to book, when to fly, and what to know before your trip.
  • If your dates are flexible, aim for a Monday departure and avoid flying on Thursday. On this route, Monday flights average £544, about £113 less than Thursday fares (17% savings) based on the last 12 months.
  • For the best chance at a low fare, aim to book around 12 weeks before you fly. On this route, that window historically saves about 18% versus last-minute pricing (KAYAK booking data, last 12 months).
  • If you can choose when to travel, plan your Sydney to Hong Kong trip for March. Fares historically average £446 return in that month – typically £435 less than the most expensive month, which is December (based on the last 12 months).
  • For the best chance of arriving on time, fly with Cathay Pacific. Over the past three months, 87% of Cathay Pacific flights from Sydney to Hong Kong arrived on time, slightly above the route average of 81%. When flights on this route arrive late, they're delayed by an average of 2h 20m, so choosing an airline with strong on-time performance can make a difference if you're on a tight schedule.
  • If you have the time, taking a 1-stop flight through Chengdu Tianfu Intl Airport (TFU) can be cheaper than flying direct. The cheapest stopover option averages £392 return on this route – about £233 less than direct flights (based on the last 12 months).
  • If you're arriving late at night and need somewhere to stay, check out these hotels close to Hong Kong Intl Airport.

    • Regal Airport Hotel
    • Regala Skycity Hotel by Regal Hotels
    • Hong Kong Skycity Marriott Hotel
  • After your flight from Sydney Kingsford Smith Airport (SYD), if you decide to take the airport express train from Hong Kong International Airport (HKG) to the city (and it is a highly recommended option), it is a good idea to buy tickets online, as the service is popular and you may otherwise have to queue for tickets. Using the Klook app to purchase tickets can save you up to 30% off the normal price.
  • Although taxis in Hong Kong are generally cheap, it can be costly to use taxis to get to and from the airport, as there are several tolls on the bridge to Chek Lap Kok Island, where the airport is situated. The Airport Express train or private shuttles booked online will generally prove more cost effective.
  • HKTaxi, a taxi hailing app, allows you to order a taxi and pay for it online without the need for cash. Visitors to Hong Kong can use this app to reserve and pay for their ride from the airport, then continue to use it for getting around the city.
