I saw the post tracking the progress of the interior mods to 767s, but Delta announced in January a bunch of changes to the interiors of their narrowbody aircraft. I'm particularly interested in the 737-800s and the A320s. Is there any information about progress on those changes? (new slightly wider seats, updated lavatories, IFE at all seats, more power outlets) I can only find a January press release but all of the info on the Delta page about their aircraft still reflect the entertainment options and seat configurations/widths of the old interiors.
