Welcome to the forums! Good to see another UA
fan here on a.net. They are my favorite airline too.
I think that the 767s could have a narrower version of the first suite. The 767-400 prototype had some sort of pod seating (1 x 2 x 1 config.) in its display, IIRC. If it did happen, it wouldnt be angled towards the windows like the 772 and 744. I don't think that anything will happen until UA
gets more funds to update its seating. I have heard RUMORS from UA
employees that they are looking into lie-flat business seats after they come out of chapter 11.
