Q: If a player has possession and is in the air for a shot, and the shot is blocked free of his hands, can he catch the ball before it hits the ground or is this traveling?
A: Similar to the question about, if the player no longer has control, the ball is considered loose and he may be the first to touch it. No traveling call would be made on this play.
The full answer is on Donnie’s website. He is the NBA’s VP of Referee Operations

That is ONLY in the NBA, in FIBA or Ontario High school or any other organized ball, you ARE allowed to rebound your own airball as long as the referee believes it as “an attempt at basket”. I added one link, but can send you 10 more
Good point Ed. It should be it’s own blog post, because while it is similar to being blocked it is one that people argue about.
