Yeah, but those one-hour claims are usually made looking at air travel routes, not from opposing points along the equator or pole-to-pole. And of course "anywhere" only includes major metropolitan areas in about a half-dozen countries,* because the rest of the world is irrelevant. Even so, they ignore trifling things like accelerating to cruise, slowing down to land, and traffic to and from the airport. But it's within the range of usually accepted puffery, at least, not total absurdity.
* US, Japan, China, Saudi Arabia, UAE, Germany, and maybe the UK if they feel generous.
