Of course diving in the morning and flying the same day is ill-advised. The common required interval is 24 hours or more-for recreational diving. You may be quite right about commercial divers whom may have exceeded "recreational" depths. However, divers DO stupid things from time to time even if they should know better for one reason or another. But really, follow good dive protocals and you will be fine.

Few people even realise that many commercial divers will not fly for 7 days after there last dive, and a few will extend that to as long as 2 weeks depending on the work and there decompression regime.

This is to prevent the onset of DCI, Decompression Sickness, better known as the bends, it is caused by changes in atmospheric pressure equal to as little as 1000 feet can bring on the bends even when a diver has been out of the water for several days or even weeks with no ill effects.

The real questions are, how many holiday makers have any idea just how dangerous it is to dive and fly, many times you hear of people diving in the morning and flying home in the afternoon, just how many of these people develop DCI, how many are miss diagnosed as Deep Vein Thrombosis (DVT), after all DVT is a common decompression injury.

Isn’t it about time someone studied just how many people who develop DVT had dived in the last 7 days, no matter how shallow, and if a link is found, isn’t it time airline made it a policy not to carry people who had dived, it may ruin a few holidays, but it also might save someone’s life.
