As they swap pax between flights that have been cx'd, inventory disappears and by Sunday everything is a B or Y fare. Tuesday through Thursday things settle out and "normal" fares appear, but some flights that are either at risk or may need to take pax from a flight that is at risk may only be selling at a B or Y fare even if the flight is empty.
I've noticed this also. Typically in past booking on Saturday/ Sunday resulted in awful options/ fares. Now I regularly look on Saturday/ Sunday . I've rebooked a number of paid J trips overseas (DL marketed) and saved couple thousand doing this. Just rebooked my upcoming NBO trip for 3rd Sat in a row. Went from having to fly KQ NBO-CDG (DL marketed) to getting AF NBO-CDG then DL CDG-SLC-LAX to now KL NBO-AMS-LAX (again DL marketed) When look during the week those options always are nearly FULL J type pricing. This has held true not just for this one trip, but I have four trips currently booked that I've done this on.
