CE used to have 34” pitch, not sure how many rows, if my memory serves me well, until I believe, Cruz came along and ripped up SH experience turning it into an LCC.
The interesting view points on the other thread, “my worst CE ever!” is that it seems people would welcome and pay for a few inches extra in CE. Since BA are now targeting the Peggy Lees, Big Spenders, and the post-corona market is remarkably different, then maybe CE needs a rethink.
