Travel or not

[181174]

During the IU& IOWA game on Saturday there was a play during the 2nd half that I was unsure on, I know it has been discussed here many times and I think I have called this play a travel a few times myself, I just wondering if it really is a travel? the play was when AJ Ratliff had the ball out by the top of the key, he caught the ball, faced the basket and then proceeded to jump in the air looking to either pass or shoot but when the defender ran at him as he was coming down, feet still in the air he dribbled the ball, the officials called it a travel after a brief delay and a huddle between the lead and the Center they decided on a travel. Just wondering if anyone saw this play and was it a travel?
