Interesting article in "Undercurrent" this month. It seems that DAN's rules about flying after diving don't apply if you make multiple flights. It cites a woman who made four flights after a dive trip, leaving 24 hours after her last dive before she commenced the journey, and ended up with severe DCS. The first was a puddle jumper (like ours), the second and third were airliners, and the last was another unpressurised light aircraft. Not much research on this yet, but maybe it's a good idea for us here on AC to advise our guests to take a night or two on the mainland before they fly home.
