QF is not the only carrier to not offer/provide PJ's on day flights. SQ does the same (in F) on day trips like MEL-SIN.
oh and some other carriers make PJ's a "secret" service.
I flew UA recently MEL-LAX.. A 15 hour flight(as we all know). PJ's were *not* offered to anyone,but I knew they had them as part of their revamped "Polaris" product(still rubbish, btw... but I digress
).. Anyway so I finally gave up waiting and I asked... and I was told sure and that PJ's were only provided "on request" - ie you had to KNOW to ASK for them - they were not offered to pax. I enquired further with sources within the airline and was told this was because they never load enough for the whole cabin. Ridiculous.
Once I got them, they were actually really comfy and better to me than the old QF F (the grey and brown ones before those) ones. Quite nice surprisingly but to have to know to ask??
So yeah....,
