11 hours in a private plane with lots of room and being able to lay down flat or be in a zero gravity chair would be sheer luxury compared to many flights I've taken. My last long distance flight took 24 hours of travel to get from San Jose to Israel with 3 legs in Coach and going through multiple security gates. One time I flew 16 hours Coach from LA to Guanzhou China and that was a second leg. My tail bone was in pain for a day from sitting that long.

If an airplane like this meant being able to fly private, it's completely worth it. One other factor you have to consider is that this plane can probably use tiny airports which shaves a 4 hours of additional driving and security gates. I'd rather be in a slower flying plane for 7 hours than fly for 4 hours but spend 4 additional hours at security gates and car traffic.
