Looking at spending some BA miles for a trip to either YVR or ANC from EZE in Biz Class. Never flown AA in fact I've never flown on any US carrier before. I think think the flight is on a 777 from EZE then connecting on to a 757 which will book into 1st I believe.as they don't have Biz on those routes. Any idea on the seating on both sectors? Lie flat beds on the 777 or older type seats? Champagne? Food? Malt whisky? Amenity kit? Gorgeous young friendly female FA's? etc.... Any advice would be appreciated thanks.
