I use to work for a Holdings company that was mainly land development but operated a carrier that flew part 121 (sub service for scheduled and some Adhoc for government) and also had part 135 (charter) operation. Our holding company had companies and locations throughout the Midwest and was always acquiring more companies. I ran IT and was also on the team that vetted companies for acquisition. Our 135 flew 2 G2's, 3 Hawkers, 1 MD-80 (nicely outfitted) and a King Air. I was on the short list of people that could schedule the planes, but knew better. Our owners were nuts and changed their disposition like grass in the wind. I always waited for them to suggest that I take a plane instead of flying commercial and they always did. Driving 1 hour to O'hare, waiting 1 hour for a flight and repeating the same the other direction was a waste of time in their eyes and I could be more productive if I drove 5 minutes to the hanger and in the air in 10. I usually flew the King Air for obvious reasons. The others were to expensive to fly and maintain, especially the G2's. The owners always took the G2's until they got the MD-80-7 (which, btw, was cheaper to maintain than the G2's). If I was going somewhere with the owners then I flew in the G2's. If it was a larger group of us without the owners (6 or so) we would take a hawker.
I say all of that to say, I really got spoiled. Being 6'4" does have its disadvantages that flying private overcomes. Then there is something to say about convenience. No airport drive, no TSA, no delays (usually), no short people reclining their seats and killing my knees. Those were the good old days. Then 2008 happened....... All of a sudden, the owners were saying, "why don't you fly commercial? You're not saving that much time." Everything changed. As the economy fell, so did our businesses. I left that company in 2011 and soon after both the 121 and the 135 filed for bankruptcy and later folded. God's timing was miraculous. I had not seen the owners since I left that company. Ironically, 2 weeks ago when I was headed to Dallas, the were on a commercial flight with me and we sat next to each other while waiting for the flight. Talk about awkward. I figure they were checking on their developments in Euless and Grapevine, TX (the only businesses of theirs that is still flourishing).
