Riker, shall I understand that you are not working for us ?
You are summarizing the point of GA charter vs Scheduled Airlines perfectly, as a general point of view. Whre I do no meet you , is that one's should not expect to make a lot of money; what is a lot of money ?
For me good money is 10k€ a month net. This is my personal welfare, others would be happy with 5k€ other would not consider living with 20k€.
Money is not everything and surely lifestyle and airplane a definite factor; the outstanding thing at Netjets is that you have the same money should you decide after being 6 years in the company to fly the C550B after having spent the last years long-hauling and reverse Jet-Lag.
As you said nothing is perfect, but it is not a reason not to try to improve it...
