Currently onboard AA181 LAX-PEK... Casper bedding is loaded with slippers... The slippers are nice and plush. Will report back my thoughts on the pillow/duvet which I am sure will be miles better than the old ones that I have complained about a lot.
Only annoyance, no PJs. IMHO flights over 12+ hours should offer PJs. Not just HKG/SYD/AKL flights.
