Can I take the ferry to HKIA to go with my luggage to a hotel near HKIA for one night til my flight next day ?

Hi, Sherif.
You can only take the ferry to the HKIA on your flight's departure day. However, if you take any of the plane in the following airlines and your flight leaves HKIA before 10:00 the next morning, you are allowed to take the ferry for HKIA. The airline companies include: KC, PX, CX, CI, KA, GA, KL, MH, TZ and AE.
