Fortune magazine online has a photo essay about their new 787. *On one

they make this statement:

The Dreamliner's wingspan is 197 feet, or about 25% longer than a
similar-sized plane, which increases lift and reduces drag.

I thought that lift, in addition to causing a net upward force on the
wing, also contributes to the drag force on the wing as well. If this
is the case then increasing lift should also increase drag. *Did I
misunderstand?

For any fixed wing geometry, increasing lift increases drag as you
say. In this case they change geometry and get more lift with less
drag. OK?
