He's certainly no couch potato! The "basket" that was used for his round the world balloon flight stopped in at Oshkosh last year on its way to NASM. It was not roomy or remotely comfortable looking, so I should think a few (80?) hours squashed in a plane should be relatively straight forward for him.
Good luck to Fossett, Branson and the Rutan team - people who push the limits as these folk do help to cheer up some pretty dreary news headlines these days!
