foul or travel?

[rsl]

A1 and B1 are both chasing a loose ball, with lots of incidental contact. A1 jumps in front of B1, controls the ball in mid air and lands with both feet simultaneously. A1's momentum, combined with a generous bump from B1, causes A1 to take a rather large hop with both feet.

Is this

(1) foul on B1
(2) travelling on A2
(3) no call

This happened in a rec league game. I could not call foul on B1, they both had equal rights to the ball and neither had position. In real time, I saw the hop and called travel, but now that I have time to think I might go with a no call. This might be a HTBT situation, but what do you think?
