Sorry if I missed this somewhere upthread or elsewhere, but is there a maximum number of CE rows on the 319 (ie a point at which the curtain can't be moved further back)? I'm booked on a short haul flight next month in ET where CE is currently rows 1-7, and rows 8-10 are blocked (presumably in case the curtain moves). I'm trying to figure out how far forward to sit where I'm unlikely to get randomly reassigned due to curtain movement. (ET is mostly open at this point.)
