He's only going to really see them on the weekends either way with his current schedule. The commenter was suggesting that, given this, it'd be more economical to just stay in SF during the week. However, the funny thing is that apartments in SF are so expensive that the $2300/month he's paying to fly on the small commuter jet is actually not that horrible of a deal compared to renting a small place in the city. So maybe he just enjoys the commute. I've flown on a private jet like this (Cessna Citation CJ2+ in my case) and it's definitely a fun experience.
