Just booked an AAward with one segment being MAD => ORD. Does the 340-300 or 340-600 fly this route? Or is it variable? The flight is not until July 2009.

I had AA book me into rows 2 and 3 (window/aisle) for a family of 4. I suppose if it is the 343 I should rebook to row 6 based on this thread. Otherwise on the 346 being a little closer to the front seems more desirable for food service.
