I take regular visits to the Boeing website, and when I look at some pictures, the wings tend to edge/point up. Why is this?

    $\begingroup$ Are you asking about winglets or flexible wings? $\endgroup$

    $\begingroup$ @Farhan I think he's referring to the dihedral angle $\endgroup$

    $\begingroup$ @TomMcW: Or it could be the upward flexing of the wings while in flight? Which has an answer here: aviation.stackexchange.com/questions/838/… $\endgroup$

All wings do flex, but in some modern airliners, the wings are built, fully or in part, with modern composites, that may deform within a larger elastic interval than metals...
