Slightly off-topic:
What is the guest policy at the SKL? Can a Raffles Class passenger bring a guest into the lounge who is travelling in Y? What if the guest is on a different flight from the host? (In my particular example, the host is travelling SQ C while the guest is a UA 1K travelling on UA in Y).
Also, it is my understanding that arriving (i.e. non-transiting) passengers do not have access to ANY lounges in SIN. Is this correct? If so, what can a passenger do if he arrives at SIN at 10:30p and must stay at the airport for an hour and a half?
