I flew on one of these (G-EUPS) for the first time in a while on Sunday, and whilst on the ground in a very hot Croatia I was reminded that there are no air vents at row 9 (or row 6). Assuming this is to do with lack of space in the overhead panels along with the lights, oxygen masks, speakers and whatnot, why don't BA remove the now-unused video screens to free up the space (and avoid carrying around a lot of unused equipment every flight)?
