At AA 777-200's are Class 1 bunks.
We are also reconfiguring all 777-200's to a 2 class config (Biz and Coach) 1st class on the 777-200's is going away.
2 per month refurb'd in Hong Kong.
Our 777-300's have the upstairs forward for Pilots crew rest and in the back upstairs for FA's.
I've flown the 777-300 3 times now. Once as FB there is no air ventilation ANYTIME below 25,000' So if you're the FB it takes about 20+ minutes to BEGIN to cool down up there.
