If wing spells truly worked don't you think you'd have already seen people flitting here and there through the sky? That should be your first clue.
No, wing spells do not work. None of the spells that will physically change your body will actually work. Perhaps you might want to spend some time learning about what magic can and cannot do. I'd suggest the book "Modern Magick" by Donald Michael Kraig as a good place to start.
