Yes, can certainly endorse comments by GalaxyChris here.
QR award inventory - at least where premium cabin seats are concerned - has been downscaled dramatically (across a whole variety of routes) in recent weeks ; and where there is availability, it is invariably being offered at the dreaded x 2 rate ……. which explains what higham44 found when attempting to book.
Standard (ie ‘normal’ rate) redemptions are becoming something of a rare species on the website. This is clearly a conscious policy change by QR management. and it remains to be seen whether a permanent - and most unwelcome - adjustment , or some sort of temporary aberration.
