looks good now list them by seat numbers

You’re cheeky, you know I can’t do that...but that aircraft was licenced to carry 9, which I assume to mean eight passengers and the pilot.
So from seats one through to 8, you have Fuddy and Yamamoto, and the Key couple sitting right behind them. That’s four.
Either in front or behind, the tourists sitting one on each side, and the photographer and the swimmer.

Four rows of two = eight people. Near enough?

There you go, the woman with the bare arms was sitting in the front on the left:

So it follows that the unnamed tourists sat in seats one and two, Fuddy and Yamamoto behind them in three and four, the Kay couple behind them in five and six, and that leaves seven and eight for the swimmer and the photographer.

All open to dispute of course, but I'm through.
