I am traveling on a oneworld F Class mileage ticket in the Fall and doing several legs on CX, but on the SIN-HKG segment I am connecting onto DXB and the day of departure there is no F-class flight which would allow same day connection in HKG onto DXB. I have choice of taking an A330 or 773 SIN-HKG same day in J or taking 744 night before into HKG in F-class. Pros and Cons both ways, but just curious if anyone had any experiences in this specific market with the J and F class product and aircraft types? Considering if I take the only F-class flight I can, I gotta spend the night in HKG and if so can I stay anywhere in the airport? Airport hotel/lounge possibility for F-class pax? Thanks for any tips! I am using a whole bunch of miles here and want to get the best "bang for the buck".
