Im guessing the 738 wuda gone out full and made the leg ok.

But its only a 160seat airframe. So maybe more frequency smaller airframes is good for a pilot list?

I wud be curious if the wgt limit issue was driven by fuel for winds. Togw ratow limits. Or cargo payload offsets.

Clt-lax is one of the legs piedmonts 727s had problems with. The 767 buy fixed that.
