From hong kong airport to Tsuen Wan, where do I purchase the one way Airport express ticket?

Oh, it's convenient. You can buy the ticket at the Customer Service Center of AE Station in HKIA, or the round counter in the arrival hall. The airport has many detailed English signs that can help you find the right direction. Don't worry.

You are suggested to take AE to get to Tsing Yi Station first.It costs 60 HKD per adult. Then take Tung Chung Line to Lai King Station and Tsuen Wan Line to Tsuen Wan Station. The ticket fare is 4.4 HKD per person. Or if you are going to a hotel in Tsuen Wan, your hotel may offer free pick-up from Tsing Yi.
