As an update to my prior post on how long you should wait after diving until flying - here is a detailed chart plotting letter group against altitude. Of course, for those who are used to using computers, better review those letter group tables. I would still wait the full 24 hours.
Also - generally, commercial flights are pressurized to 8,000 or so feet. Though, I would hate to depend on that assumption and be at 30,000 feet when the plane has a sudden loss of pressurization. Yikes.

Perhaps the dehydration thing is a concern, but the real concern is pressurization (or lack thereof). Someone above said commercial cabins were pressurized to 8000 ft. You wouldn't want to come out of a dive and go immediately up a mountain, right? That's the same reason you don't want to fly: you've still got gasses in your tissues and they'll be fine at sea level, but you could wind up with the bends if you fly . . . .
. . . . HIGH . . .
The inter-island planes in FP do not fly at 30,000 feet. You can dive and fly all you want between PPT and MOZ since that puddle jumper flies at maybe 1000 ft and the flight time is 10 minutes. Between other islands, I'm guessing you are flying at maybe 10,000 ft - so high enough to warrant caution. I'd use an 18 hour rule on inter island flights. OK to do a morning dive on Day 1 (out by noon) and then OK to take an inter island flight the morning of Day 2.
Apply the 24 hour rule before your international flight home.
