At least in the past, Intel owned a dozen 35-50 pax regional jets (https://www.planespotters.net/airline/Intel-Air-Shuttle-Airc...) and had regular scheduled flights back and forth between their Santa Clara, Phoenix, and Portland offices. (They now seem to be down to two- rise of Zoom?)
Note that these were NOT executive jets for C-suite, these were for all employees who had meetings at other locations (at least according to people I've met since I moved to AZ a few years ago to be near my in-laws).
I remember the airplane tail had the number 386, or 486. It was difficult to get a seat, but it was based on first come first serve, so you just had to be diligent on the booking web site.
Coming out of San Jose, the plane would enter this corkscrew to gain altitude. I guess to avoid SFO airspace.
I would often see high level executives on the same plane.
