How do you even manage that? If you fly first class every hour of every day that would still be impossible. So I guess the man charters entire airplanes?
It probably includes staff travelling costs, security etc.
Flying first class is for peasants.
They fly a official plane and bring a lot of people with it. There was a plan to replace the place, but for the time it got backlashed so hard they put the idea aside, for now at least.
