MA has suspended their TATL service for the winter (thanks to their new Russian ownership), and if/when they resume service it will be with new planes. So all of the details will be different, and maybe there will even be real J seats in the "new" planes (right now it looks like these will be 763s, so new to MA but not new from the Boeing factory). Oneworld is probably pretty unhappy about what happened to MA ownership, but we'll see.
