I'm planning a rtw and have already heard of the best lounges for each airline which is usually in their hub city/cities. For Qantas (SYD,MEL), Cathay Pacific (HKG), British Airways (LHR) and so on. I was wondering which lounges not operated by their own city people think are the best. For example, the terraces lounge (BA) in New York JFK seems to get good reviews. If people could comment on different OW lounges they've been to, it would be appreciated. Thanks.
