Hong Kong can be reached by air as well as by rail. A flight from Beijing costs around RMB 2,500 round trip, though prices vary by season and are generally higher on weekends. A cheaper option is to fly to Shenzhen first and take the train from there — the ride to Hong Kong takes about 30 minutes.
The airport is about 45 km from the city center. The fastest way in is the Airport Express, running from Hong Kong International Airport via Kowloon Station and Tsing Yi to Central. A one-way ticket costs HK$90 (discounted group rates from 3 people, HK$210 total), and the ride takes about 25 minutes.
In-town check-in is available at Central Station, from 24 hours before departure up to 90 minutes before your flight.
