Cathay Pacific Asia Miles - HKG-BOM CX684/685 330 sub for 33B

Today's CX684 is being operated by 330 instead of standard 33B. The sticky FAQ mentions that 333 (old long haul J) is a possible sub for 33B, but it appears that CX is also willing to sub a 330 (regional J) for a 33B.

Perhaps FAQ should be updated to reflect that it's possible pax may get stuck with regional J on this sector and old Y seats without AVOD.

Having booked this flight in F as 74A for August, I would throw a serious wobbly if I found myself in regional J having paid for F. This is now a long way beyond acceptable in my view.
