Different country, different era. But my uncle worked for Lockheed in San Jose. He used to have to go to their Texas plant about 3 times a year. Lockheed flew a daily L1011 between the two plants and, if there was space available, he flew on it. If not, he flew commercial. It's a truism that, as communications improve, and thus more people interact remotely, the need for face-to-face time also increases.
