The general recommendation for PADI divers is based on the typical
cabin altitude in pressurized airliners of around 8k feet, with the
potential for decompression as well. I will quote the text verbatim from
the 1990 version of their open water dive manual. I'm sure that there
are later versions out there with prettier colors and pictures, but the
basics are pretty universal.

1) if you've made a single no-decompression dive with less than 1 hour
of bottom time, wait at least 4 hours

2) if you have made a signle no-decompression dive with more than 1 hour
of bottom time, or if you have made a repetitive dive, wait at least 12
hours.

3) If you've made any dive requiring EMERGENCY (emphasis mine)
decompression, wait at least 24 hours.

The text goes on to state these are minimums only, and that whenever
possible a 24 hour wait is advised in all cases. Emergency decompression
applies to an unplanned stop, not your routine "safety stops" they
recommend. Of course, you can dive by the book, and never bust a limit
and still possibly get bent afterwards without ever getting on a plane..
people are individuals.

My personal stance is if I'm going to fly-in to a dive trip, I will at
least spend the night and depart the next morning. But, if I had to make
a quick turn, I guess I would be in for a low altitude trip all the way
back.

Hi Michael,

a "Fly-in SCUBA trip" seems somewhat contradictionary to me, as the
nitrogen accumulation aquired during SCUBA-Diving restricts even
commercial flying for up to 24 hours after a dive. General
recommendation for PADI-Divers is to refrain from diving for 24 hours
before commencing a flight. So unless you plan on staying several days,
your diving would have be very limited.

regards,
Friedrich
