To really split hairs; after a flight you can be significantly below saturation at 1 atm (effectively a negative pressure group). Might this indicate the possibility of longer than normal NDLs?
Unfortunately, Steve, No.

I asked this question during OW class, again during Nitrox class, DM class and even of an Advanced Gas instructor. The answer was the same each time.

The nitrogen loading between the time you managed to get off the plane, on to the boat and into the water would be such that the "residual" negative group would have returned to practically the same as if you hadn't flown at all.

Good try, though...
