IME even when F is served as J, the flowers are often there. Also IME, the amenities are often F class (Aesop).

i think this will change with the upcoming elimination of regional F. As well as the closed curtains / extra staff, mentioned above (also a nice perk). Based on what has been mentioned elsewhere in this forum, it sounds like it will become more like the KA "F served as J" or "j served as Y" situation.

CX had kinda done this hybrid, where staffing levels were for F and it was served as F just with J food. The best flight I've had in a long time was SYD-HKG earlier this year as such. Me and Mrs QRC, plus two others (one DM one GO IIRC) had F to ourselves and superb service. Curtains closed, dine on demand (with J food), ate together with the extender, pax even sent back to "J' trying to use the "F" bathroom! Aesop in the bathroom. 2 crew just for "F".

My guess is that situation goes away when the rostering levels change.
