I just started air layering a month ago. One air layer has quite a few roots. I have pictures on another post. Check the pictures and as deerhunter16 John mentioned in the thread and showed his current air layer - there are a lot of roots. So I will still leave mine to produce more roots.
John (opiem10) did very extensive step-by-step instructions on how to air layer in the posts. Just check through them. Or ask questions, everyone here is so helpful.
