I think the exTOM 767s are quite different internally to the exFCA ones. The exTOM planes have less width per passenger since more seats are squeezed in widthwise. Also the Premium area on exTOM stops at row 5, so row 9 might (or might not) have a window on these, and I don't know for certain whether row 19 is the one in fromnt of the exits which suffers from no recline.
To make things a little more complicated unfortunately, I think the exTOM planes might be being reconfigured at present to help absorb the seating shortage caused by the late delivery of the Dreamliners.
So - if you are going to be on an exTOM maybe one of the experts BY-TOM-FCA or Darren might be able to give you more info. Good luck with the flights - but have a great time in Mexico.
I totally agree about removing the recline facility altogether on ALL seats. If it didn't exist there would be far less complaints from folk who have suffered due to inconsiderate people in front.
