I'm assuming you're saying the new configured F cabin is cool, and not the temp of the cabin. One of my big pet peeves w/ UA is them keeping the cabin temp too high, which makes it difficult to sleep. Flew 767 Int'l F just a few weeks ago & cabin was too hot. It cools down when they want you to wake up/brekkie, and it's a noticeable difference. Been a pet peeve of mine for years w/ UA.
How does a passenger in UA F regulate the entire cabin temp? Did I miss something? Wouldn't there be fisticuffs btwn passengers when some like it warm & others like it cool?
And hey, you get PJs on LH. I flew LH F on the way back 2 weeks ago. My plane matched the pics farther up in the thread. FCT rocks; 'nuf said.
Speaking only for myself, I'm not going to complain about Int'l F class, regardless of carrier.
Cheers.
