Just to remind you that there are NO emergency exits on row 15. The emergency exits are on rows 16/17.
As for more leg room, there is more leg room in rows 1ABC, 2DEF and 16/17. Get a priority boarding ticket and you'll get first in the a/c and then you can sit wherever you please.... As for blocking the rows.. There are only 2 simple rules wich pax like some on this thread believe crew are blocking rows just for fun (sense the sarcasm) : if there is a less number of pax than the capacity of the a/c the crew will block off rows 1 to 6 and 29 to 33, or only row 3 and 4 FOR THE WEIGHT AND BALANCE OF THE A/C FOR TAKE OFF AND LANDING!!!!!!
So before you b!tch and moan ask yourself "maybe there could be a reason for this?"
Respect,
