Thanks for all the comments! And also the link to the research paper. It's along the lines of what I was thinking already.

I agree with you in concept, but I am curious were you got the 3 hr SI from? Can you help me out?If you'll do a multiple dive you'll need to wait 18-24 hours. If you do a shallow dive 5-7m for about 30-40 minutes similar to a DSD you should be ok to fly 3 three hours after the dive. Non multiple dives. It's better to be safe than sorry. follow give guide lines and SI stick within flying guidelines and enjoy even a shallow dive. Better than nothing.
Have fun diving and enjoy!!!
Here's a good place to start: http://www.ndc.noaa.gov/pdfs/USNDeco3.pdfI've cut it shorter than 18 hours and not had any issues...however, I prefer to be safe and try not to fly within 18 hours of exiting the water. Fortunately I my travel has slowed greatly this year and that's not been an issue!
I've always been interested in this topic though and I think I'm going to do some more research on this for my own edification.
I've occasionly cut this a little short and have gotten away with it so far.
Nick, I'm with you. And I know, for example, that last year's PNW DYFO crew got off the boat and drove to the airport, after three days of four dives a day, some of them moderately deep recreational dives. I'm too liability averse to recommend that anyone else do that, but I do it, and my friends do it (including you guys!)
I have heard it said that if you get bent on an airplane, you were bent before you got on, which makes a lot of sense to me.
I remember reading an account of some research on time to fly, which indicated that technical divers could use SHORTER times to fly than recreational divers -- which has always made me wonder if the problem with flying after diving for a lot of folks is a combination of diving the wrong gas and using poor ascent procedures.
Now there's a deco planning tool called Ultimate Planner with no-fly time acceleration feature. It's not free and I'm biased
It incorporates both VPM-B and Buhlmann with Gradient Factors. It doesn't aim at calculating the no-fly time. It just accelerates your pre-flight surface interval, whatever it is.Asser,
I have heard a lot of people talking about your new software, but no one who has actually used it. It is based on the V-Planner if my understanding is correct ?
It treats your time on the surface as a decostop breathing air and the flight pressure as the ascent to surface ?
