Can you talk about flying pokemon because it is the best type. Such an underrated type. Are there certain traits/habits that all or many flying type share?

It is indeed, anonymous!

Unfortunately, because the flying type consists of species such as butterfree, jumpluff, minior, pidgeot, charizard, and so on and so forth, the answer to your final question is…

…all of them can suspend their bodies in the air and can be taught, either naturally or through tutoring, flying-type techniques.
