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?

Are you asking about that bent bit at the end? (Winglets - see this question for a picture) – Dan Pichelman Oct 26 '17 at 17:43

1@Farhan I think he's referring to the dihedral angle – TomMcW Oct 26 '17 at 17:45

1@TomMcW: Or it could be the upward flexing of the wings while in flight? Which has an answer here: https://aviation.stackexchange.com/questions/838/what-are-the-effects-of-the-boeing-787s-very-flexible-wings – jamesqf Oct 26 '17 at 19:10

The quality of the answer depends on the quality of the question you ask - ask clearly, precisely, and concisely. Also, welcome to Aviation Stack Exchange! : ) – Oct 28 '17 at 12:21

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...
