The flight was only nonstop on the eastbound, all westbound ops stopped in California.

Careful with this.
Water has nothing to do with ETOPS per se, it just acts as an agent of separation: along with deserts, plains, and overnight closures. Non-ETOPS twinjets can and have crossed the Atlantic nonstop in scheduled service.

As stated, that's because DL has elected to op most of their 752 fleet at lower MTOWs to save on costs, due to the general operational profile assigned to those aircraft for the majority of their service life.

Though that's technically untrue, for realworld situations, it's close enough:
Older 757s have a fuel capacity of 11,276g; whereas most newer ones were built with the 11,489g capacity.
