Most of my travels the past several years has involved Delta transatlantic flights. Haven't been on AA in about 5 years.
WIll be flying JFK - Athens, and looking at both Delta & AA. THe Biz Class RT flight on AA is almost 2G less than on Delta. But I'm a little confused when I look see Business Class and then there's a Premier business class. What does "regular" Biz class not have that Premier has? THe website says Premier has the best seats - but are they in the same cabin, with different seats?

Currently, which provides a better experience - Delta or AA? THe AA flight would be on a 777-200. For 2 people to sit together, is it best to take 2 middle seats, or window seats? it looks like in the middle you stare at the person in front or in back of you, not next to you?

Thanks
