If it sounds too good to be true, it probably isn't.
From what I read and heard, in the SQ incident at Taipei on Halloween a few years ago, the Singapore Girls performed despicably in the evacuation of the passengers from the aircraft. Singapore Girls may be great for service, however, when it comes to safety, in their one true test, it appears that they failed miserably.
By comparison, in the evacuation I was a part of with United at Denver about 15 years ago, the cabin crew handled the situation consistent with their proper training, and cleared the aircraft quickly with few injuries. Of course, the severity of the accident was not the same as SQ at TPE.
I recently flew an EWR-AMS and return with them in Raffles class, one of my first flights with SQ in years , and cannot say that I was thoroughly impressed. The 744 I flew on was beautiful, the seats were moderately comfortable, and the food was average. That famous Singapore hospitality was somewhat lacking on the outbound, inbound was OK. The flight attendant that handled my side of the cabin on EWR-AMS did not speak English well at all, and was quite cold in response to my seatmate's request of an extra napkin to clean up a drink spilled in some turbulence, although she did comply. Later in the flight, a passenger across the aisle from me had just woken up, and wanted to know how to use the IFE (outstanding, by the way). The attendant came over, issued a rude reply, and very quickly explained the use of the system, and disappeared behind the galley. Returning, the F/A was more the norm, but I really didn't share the same excellent view of their service that some other members here have. To be honest, I would much rather take BusinessFirst over, even on a 767-200, and know that I'm traveling on a proven commodity (to me).
