I am asking this question since I am sitting here in the Cathay Pacific Lounge 'The Wing' in Hong Kong airport (Gate 2 - just left of customs on the airside). It is very nice, excellent food and spacious. I regularly visit and also really enjoy 'The Pier' near Gate 63 which offers massages.
However, I do think my favorite lounge is Qantas flagship in Sydney which offers a ton of perks that include massage, menu, etc.
Do you have any favorite airport lounge and why?
