I think you are underestimating how much people travelled before airplanes were a thing. First of all pre airplane there was a lot of sea travel, which was accomplished by burning ludicrous amounts of coal to generate steam power. And long road trips used to be a cultural pass time. This is why Route 66 is to some extent still such a cultural / historical icon. It used to be that American middle class families loaded into a gas guzzling vehicle to drive cross country for vacation.
