For ALL of my scheduled deadheads for MANY years into HKG ... If I had a scheduled d/h, I went to the airport arrivals hotel desk (The hotel is responsible for crew transportation) and identified myself as FedEx CREW. They always put me in a VERY NICE Mercedes limo to the hotel. Direct bill to FDX. Couldn't be any nicer or easier.
I highly recommend it.
To get to the "HOTEL DESK" ... exit customs, walk towards the opposite (north) end of the terminal, hotel desks are on the right (east) side.
