GP is referring to the deregulation of the late 1970s. Before that, there were a large number of smaller regional airlines in the US, that have since mostly disappeared.

Of course, here in the 2020s the tables have turned.
Compared to SEPTA (Philly's bus system) this seems way off base. Yes, it takes longer to take the bus than to drive yourself because the bus has to stop for passengers. But your own car will still have to stop at red lights, wait for pedestrians, etc., nearly as much as a bus. I can see 30-45 minutes for a bus ride comparable to a 20 minute direct drive, but any more than that points to some other problem with your city's roads.
