>>1144932Technically you could probably turn any cargo aircraft into a passenger aircraft. Practically it most likely wouldn't make much sense, I may be way off base here but I think it might be akin to using a semi-truck as a bus.
Additionally, historically whilst everybody is impressed by large aircraft that haul hundreds of passengers there does appear to be a finite number that companies are willing to carry per trip. Regardless of the logistics of your transits hubs being able to deal with 1000 passengers per trip, can you guarantee you will get 1000 every time. Airlines now seem to be happy with something that will carry between 250-350 pax.
