Just a little FYI...
The days can be quite short, 1 or 2 sectors (though a rarity). In saying that, 3-4 sectors are the norm. Often PER flights on the 330 are direct, while the 737 can be a mix of direct or 2 sector days.
Although in a lot of cases, it's less about the days and more about the rest in between.
