If we’re going to establish a definition of the working class as distinct from petite bourgeois, a good dividing line is measured in the time and resources necessary to engage in this kind of travel and performance.

You could define class like that, according to that line you just made up for the purpose of your argument, or you could use the definition of class that Marxists have been using since Marx himself, which is based on roles in the productive process and relationships to the means of production / other people’s labor power. I’ll stick with the Marxist view, and not come up with an entirely new definition based on an article about 2 out of 20,000 people who took a private jet to DC.
