No MCE for our party of 4 on AAdvantage awards DFW-LHR next spring so am wondering about a strategy to make it through the 9 hour flight. Safer to go with row 27 middle section of 4 or try to go for the window and aisle seats along the sides hoping that the middle seat will remain empty? I realize the further back in the plane the greater the chances of this working out. Are these flights typically full? Also is the in seat video on demand in the 777W or do they just show everyone the same movies? It seems that the AA website references this both ways.
