Actually, I won't make an extra connection to JFK from Boston just to get the extra premium service (more segments means more chances for delays).
But I'll occasionally combine a LAX and a NYC trip so I can fly between the two. If your aircraft is a 763, you'll be in an int'l aircraft, which means electronic F seats (same as the current non-suite 744 seats), and biz has all the bells and whistles.
There is a similar thread about AA's premium service ("3-Class Flagship Service") on the AA board. First posted by onedog, I believe.
