It’s another MOL publicity stunt. Punters might be prepared to put up with a 2 hour flight in a high density 738, but 6+ hours is another matter, especially on the overnight eastbounds in seats with no recline.
What metal would he fly them on? 738s are out of the question. Maybe he could take some of BA’s soon-to-be-retired 767s.
Good luck to him, but others have tried and failed and I can’t see this being any different.
