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.
Not an issue if you are primary a non-airbridge airline that use both doors and serve from both ends using 2 trolleys and 4 crew, plus a microwaveing runner when more than 200 seats.
Even if you use airbridges occasionally you can still use the back door for unloading with stairs and back up again onto the airbridge.
