Are there much J/F Savers left on popular routes? I wonder if SQ PPS members will get a lot more availabilities on those.
PPS members should definitely have a lot more leverage in this regard.
Not sure about Saver, but sometimes it's not a case of Saver vs Advantage (vs Access), it's just is there any availability at all (unless you have cash to pay).
Having talked to someone in the Suites cabin when I was fortunate to find a seat on that flight (Advantage, of course), they seem to imply that Suites seats on points are much easier for PPS members to access, which sometimes can result in no more award seats being available for the rest of the members for days at times.
As a side note: SIN KF J lounge at T3 last Friday evening had no free seats avail around 10pm so we walked out! A380 (Sq 231) to Syd in J was packed...
The SQ lounges would be absolutely slammed at that time of night - all the late night departures to Europe, North Asia and Australia, with the widebodies and all - definitely peak traffic well until after midnight. Even TPR, while obviously not as ridiculous, would be quite heavy in traffic (i.e. no luck getting a sleeping room; may even be really busy trying to get a shower).
If J was packed on that flight, then I guess SQ must be thinking they're doing something right

(viz 100% load factor, particularly with
that many J seats).
