I was sad to see the pillows and blankets go not because I use them, but because I enjoy cooler cabins (warm ones seem claustrophobic to me--on warm redeyes, everyone else seems to snooze away while I suck down ice water to stay cool), and I wonder whether we`ll see higher temps now.
Recently, I did Qantas' SYD-SFO flight where temps were cool the whole flight (but hey, we had blankets). An excellent flight for sleeping or dozing.
