HSD,
Thanks for that. Am I alone in thinking that 24 degrees is FAR too hot for a default cabin temperature, particularly on overnight flights? Do people normally keep their bedrooms at that? Personally I would prefer somewhere around 18 degrees - as I said, it's far easier for someone who's cold to get a blanket than it is for someone who's too hot to start stripping off.

Hey, TightSlot...
"...Not once have I met a pilot who admitted to switching off packs to save fuel, or to even feeling pressured to do so...."
If you switch all the packs off you'd be blue in the face, as packs are not just for conditioned air, but primarily for pressurization.

I remember when BA first introduced "Sleeper Service" in First around 1993 they issued all passengers in the cabin with a luxurious filled duvet.
Thick duvet = hot and sweaty passengers. So the cabin temp was turned down.
Which meant that the punters in Club were shivering under their polyester blankets!

....... Takenthe5th touched on a good point.
As the bleed air is taken, cooled, then fed to the aircon packs, a small but significant fuel saving is to be had by recirculating the cabin air.. ergo less bleed air required for a given cabin temperature, better fuel economy = happy accountants.
Its bad enough for a passenger knowing that you may well be breathing in the latest flu variants donated by a dozen transit pax from Hong Kong..
For the folks who fly up to 6 sectors a day looking after your comfort and safety, it becomes a real health issue, my take on using recirc is that it is very useful for keeping the (empty) aircraft cool on a long turnaround at a hot airport, or likewise warm during the winter months, pax on board = fresh air.

I am currently working on 737 and the A320 family. It is true that on the 737 (Flaps knows how much I love that plane 
) there is a temperature problem, especially at doors/ emergency issues level (the galleys are flying igloos
) .
On the A320 family we never have that kind of problem, even if the Captain or FO (or both) is a woman
The best solution however is on planes with cabin-controlled temperature. Less waste of time requesting adjustments and what's more, when you ask the F/D you never know the increase/decrease you are going to get, while, being on the cabin already, you are the best judge to decide the degree of change it needs. On those planes the minimum temperature is usually (on my experience) set around 18°, with a 7-8 degrees range. Usually you get the less complaints at 24°, with 20° being far too cold even for crew who are moving around.
