yes cathay is still using terminal 2. actually terminal 2 is quite pleasant. as a local, i prefer terminal 2 over terminal 3. the only two things that make terminal 2 not so pleasant is the lounge and cramped boarding gate waiting area. but for business class passenger, cathay has a separate check-in area where the staff will check you in, a porter will tag your luggage and drop it at the regular check in counter, and whisk you in straight to the lounge while the staff process your passport and other immigration mumbo jumbo. then the staff will return your passport to you while you sit nicely in the lounge
