generally speaking I keep to around 2000ft, not for any diving related intention but mostly the airpspace on the routes home is restrictive and I can't be bothered to file and fly the airways for fairly short trips!
There are a huge number of myths about diving and flying and most of them are untrue or generated by litigation fearing agencies seeking to give advice that will prevent them getting sued.
Understanding how people get bent and what predisposes you to it is an inexact science at best. I have known people dive with me in a weeks worth of deep wreck dives to 130m daily without problem yet someone who came along with us dived to 10m and on a single dive and came up bent.
At the end of the day if you have a bubble seeding that is going to cause a bend flying or not is going to make little difference.
Without blowing my own trumpet, outside of the PPrune world I am recognised as an authority on the subject and I dont have all the answers!
