CO doesn't offer F on EWR-HKG, it is only business class ... so you will get zero first class amenities (CX does have F service JFK-HKG and has a luxurious service, complete with flat beds, caviar and personal space equal to 8 coach seats). That said, this is CO's flagship route so you will get CO at its best. I have no idea what that is like (I fly CX instead). Maybe you can do a trip report and let us know what CO is like.
