Dear Sirs,

I will be back to Indonesia from Shenzhen to HKIA. Cathay gives me a reference to HKIA as CX9822 at 17:00.
My Questions:
1. May I go to HKIA erlier? As reference, to Hong Kong Airport they have time table: 07:15, 08:30, 10:00, 11:15, 12:15, 13:30, 14:30.
2. Where will I check in and give my luggage?

Thanks in advance.

Regard,
