It's not very new, though maybe more common. Around 2001, the dotcom startup I worked for was bought by a Bay Area company, and I commuted weekly from Portland to San Jose for a year on what we called the 'nerd bird'. There were a lot of us in those days, working for many different companies. I remember I found a way to get cheap first class upgrades, since I hated flying and could get a stiff drink or two before takeoff.
