Direct operating costs per seat mile for the -300 were good, but it took so long to turn that it took a serious hit for productivity. Single aisle becomes problematic when you get much over 200 seats - twin aisle simply works better when you get much above 200 seats.
I think you missed one little aspect; I once travelled on an A319 operated by Air Canada, with atrocious seat pitch. At one point the queue for the toilets, both at the rear, was 50% the way down the aisle. Had the seat pitch allowed 20 less seats this issue would have been better. Post Covid will be see better seating? Here's hoping
