Absolutely agree - cabin is always WAY too hot for me on long hauls at night. To be fair, I tend to sleep in a cold room at home (16-17 degrees C) but I do find BA cabins unbearably hot most of the time - to the point where I can struggle to sleep even in F - one flight to KUL was especially bad, must have been 28-29 degrees C on board, woke up over India with several hours still to run, drenched in sweat...looked around the cabin and half of Club World is awake with me for the same reason

weird - I always now ask the crew of possible not to crank up the heating too much!
