I suppose I am lucky that my experience with the BA shorthaul product is limited to domestics from MAN (and LBA when BA can be bothered to run them). Because of this, I will spend less time on BA’s 29” minimal padding seats than I do on my daily commute with 26” seat pitch seats with less than 1” of foam padding at times. At least I can guarantee an UD seat though.
I pity anyone with a flight longer than 1hour to suffer these new seats, looking at them.
