I appreciate all the feedback!
What I've learned is that my income on the bizjet side is very good for what I do (about 100K GBP), especially considering I fly only 300 or so hours per year. The downside is that I am based in the UK but paid in USD, which is good right now, but when the market goes the other way, I make a lot less. The other part of the downside is that I have no schedule whatsoever ~ I am on call 24/7, though the boss rarely ever gives me less than 24 hours notice. I usually know our flying schedule for a week in advance, sometimes longer. That is very hard for some to deal with.
Another plus, though, is that I fly a sexy bizjet, and I keep my overnight bags in my own closet onboard and everything is laid out and equipped as I like it and no one but me or my F/O touches anything in that airplane ~ it's as if I own it. The other perk is that we usually stay in nice suites in hotels that our boss owns in the south of France and other nice places, and our layovers are typically several days, so you can definitely relax a bit and enjoy the scenery.
I did the regional airline thing years ago, and sometimes I find myself really missing the ability to make plans based on my "line" or monthly trip schedule, and the ability to do trip trades with other pilots. One of the things I really enjoy now is that I do more than just drive the airplane. I do all the flight planning, choose the routes, choose the FBOs we use, and so much more, especially when the boss wants to go to places I haven't flown into before. And that is a lot of fun to me!
