It's been a couple of years since I've flown SQ in J. My boarding pass says I board in Group 2, on a flight where J is the highest class of service offered. And I'm *G. That beats even Air Canada for exclusivity, which puts me in Group 2 as *G unless I am booked in J on their flights.

Is Group 1 reserved for PPS, or what? There is no First Class from SIN to PER.
