HK$120 respectively. Tickets are available at all MTR stations and the MTR online booking service. Although no entry gates are provided at Airport station, passengers must still buy tickets from the ticket machines located in the Arrivals Hall, on platform 1 of the airport before boarding the train or at destination platforms. Various discounts and rewards programmes are available, such as Group Ticket Discount, free taxi connections, Rewarding programme, Asia Miles programme, etc. Passengers may also buy discounted tickets from local travel agents. Discounts are available for groups of two to four people. Hong Kong residents can also obtain discount coupons, such as those sent from credit card companies. Discounted fares are available to airport staff to encourage commuting on the Airport Express. Same-day return discount will be given to Octopus card users who have stayed in AsiaWorld–Expo for at least one hour. The discounted fare costs HK$72, HK$64, and HK$42 from Hong Kong, Kowloon, and Tsing Yi stations respectively, and includes a free connection with other MTR lines. A single trip from the Airport to AsiaWorld–Expo is HK$5. Given their separate fair structure, Airport Express journeys require an out-of-system transfer if coming from or going to other MTR lines that call at the same or connected stations (e.g. coming from Central towards Hong Kong station or transferring between Airport Express and Tung Chung line trains). However, Airport Express passengers using Octopus cards can connect with all other MTR lines for free in conjunction with the Airport Express journey within one hour of arrival at an Airport Express station. In March 2010, the MTR began to replace the magnetic tickets used for single, group, and multiple journey tickets with new "smart tickets" that contain a memory chip. The new system was in full operation by 5 June 2010. Due to the high fares and small catchment areas of the Airport Express stations, some travellers may instead choose to either use the cheaper, local Tung Chung line combined with a bus route, or make their entire journey by bus. Patronage on the Airport Express is cannibalised by the Tung Chung line running mostly on the same track. Morning Express Service The Morning Express Service is a special promotional service, allowing passengers from Tsing Yi and Kowloon stations to travel to Hong Kong station to get to work daily (excluding Sundays and public holidays) from 7am to 10am for HK$20.
