I am assuming they were flying on an ex-QF A330.
I doubt it would be policy to try and sell more blankets.
The FAAA, the QF OH&S people and engineering have been in constant battles about the cabin temperatures on the A330 aircraft, ever since they entered service. The particular problem areas are around the galleys and anywhere within a few rows of exits. Something to do with the placement of bulkheads affecting the air-conditioning flow (I was once told by an engineer). Some zones of the A330's eg J/C are always too hot, some zones are always too cold.
It was the reason that QF allowed cabin crew to wear their own knitwear, as it could not be resolved (and the OH&S department had to allow crew to wear something warm, yet QF would not supply knitwear - typical
).
I recently paxed on a CX A330 in J/C, I have never been in such a high temperature in an aircraft cabin in my life, it honestly made me feel sick
That's why I say: "If it's not Boeing - I'm not going" LOL
