Surely he'd be planning to show more up-to-date movies than that?
The total mission perspective is missing. It will still take an hour to get TO the airport, two to three hours wat AT the airport and then another hour at the arrival airport before you are released to find a cab to your destination. So for a Sydney-LA run you's spend 4-6 hours on the ground and 7 in the air. For a Heathrow to New York run you'd still spend 4-6 hours on the ground for less than four in the air. It would be similar for Heathrow to Chicago except that you'd spent another three hours trying to find the scumbag of a baggage handler who vandalised your gear and nicked your valuables.
The airport is the bottleneck, and it would surely be far cheaper and more cost-effective to invest in ways to reduce these delays than to invest in decidedly speculative high speed aeroplanes for the flying segment.
Mach 2.2 presumably means significantly higher than FL600. There's no mention of how the radiation problems would be addressed.
