Other North & South America Frequent Flyer Programs - AM in Y MEX-GRU?

I got a very cheap ticket OW MEX-GRU in Y on AM; NW EQMs, and hundreds of dollars cheaper than anyone else OW (about $465 all-in JFK-MEX-GRU).
I've flown AM on LAX and JFK-MEX, so have an idea of their Y class service on North America flights. But I've never flown their 767s.
How is Y service on MEX-GRU? Similar to US airlines on the route, I assume? (e.g., no PTVs, no electrical outlet, a decent hot meal after take-off and a light breakfast before landing, along with OK-but-never-great service)?
Or, by chance, do they offer PTVs or power ports? A boy can dream....
Thanks in Advance!

GRU is one of AM's flagship routes along CDG and MAD. Therefore AM deploys the B777 to GRU 6 x week while 1 x week it uses the B767. The B777 have AVOD system, power oulet and offer AM's newest product. You will certainly have a better experience with AM as compared to US carriers.

Rgs,

Whoops!
I wrote the wrong destination.... I'm actually flying a longer route, JFK-MEX-EZE. And it's not on a 777, it's on a 767! So I'm guessing everything you wrote is actually different on their 767s?
Thanks!
