The number of people who will pay--or can make their companies pay--$500+/hour for a handful of saved hours on a flight which mostly won't go into incremental productive work is miniscule. Most business travelers aren't international lawyers or consultants flying across the Atlantic for a quick get together. But pay a bit more to fly a bit more comfortably to be more rested/as a perk and maybe even save on a hotel room night? Quite a few people, even if not the typical traveler.
