I dont know how you are swaping in FAT, only 1 day had over 3 reserves. Unless they were on the same days as the trip you wanted to exchange, there is no way to get around min reserve staffing.... But at the same time I dont really want to swap for one of those awesome 15 hr 4 days that are available as open time in fat.

Those 28/29 leg 4 days crediting 24 hrs sure looks painful out of PSP and LAX.
