Chevvron, both airfields are still very much used by Loganair, and it still is the shortest scheduled route in the world, as far as I know.
The ferry service between the two islands is about 25 minutes, as the jetty on Westray is a bit further south, and therefore further away from Papa Westray. I've never flown between the two but landed at Papay (as Papa Westray is known to locals) on the way between Kirkwall and North Ronaldsay.
