If you look on this problem from the other side it may be interesting.
You have spent 7-digit amount on bizjet to get comfort, convinience and flexibility.
Your annual budget to keep it going is much much more than you would pay for 1st class tickets.
Your flight crew is paid somewhat similar to high level managers, the only difference that managers making money for the company, not just spending.
Now you need to get to New Zealand for a meeting and your wonderful flight crew is saying "sorry but this beyond our FTL... you wouldn't mind to spend a night in Bangkok while we have a rest, don't you, boss? or may be you would take a scheduled flight?"
