WARNING: I rate (and have REALLY enjoyed) EY J highly. If travelling alone go for window, if a couple go for the center,
Depends if you enjoy flying in J? Eating some extra meals (no making or cleaning up after yourself), watching more movies (without the phone ringing or being nagged), sampling several champagnes/wines and that extra dessert or three...
Some look at cost / time others look at time involved - your call. If I had the time available (not restricted to one day less available time on the ground at destination for example)...
Provided I have slimmed down in the lead up then extra J flying time is my choice.
