And the problem that airlines have faced the the 757 is that it is over-engineered. It's large wing and powerful engines not only make it very capable, but also make it heavier and more expensive to operate on sectors that don't require these capabilities. Especially since the almost-as-large and far lighter 737-900 has come along. Thus, as pointed out, the niche that it now fills is as a high-volume European charter carrier and as a low volume TATL transport.
