The Airport Express also offers flight check-in facilities at Kowloon station and Hong Kong station—the in-town check-ins offer a more convenient and time-saving routine; a free shuttle bus service transports travellers from these stations to their respective hotels as well. Porters are also available to help transport luggage from and onto trains. It is the second most popular means of transport to the airport after buses. In 2012, it had a 21.8 per cent of share of the traffic to and from the airport. However, this has declined from a peak of 32 per cent in 1999.
