For ground handling, narrow bodies win. Especially LCC/charter ops on bucket and spade routes. Above wing I can see how a twin aisle is more attractive. However, below wing it needs to be something that can be bulk loaded quickly and easily. Thinking of UK regional bases and greek islands with seasonal staffing and limited capacity the last thing you want to be doing is messing about with ULD's and high loaders. This is the big difference between the 75/76.
