V. - you have a good idea ... you should post it in the "wish list" forum, or whatever it's called (can't think at the moment). Perhaps all staff salaries could queue off the pilots you have hired so that if you change your strategy mid-scenario the salaries will adjust accordingly.
But, even with the current v1.2 a regional carrier can succeed provided you properly match demand with approporiate a/c and turn over the seats a minimum of 6-8 times per day. This means not "reaching" for demand on longer distance routes. This said, there aern't too many airports (at least in North America) with enough close, decent regional routes to make much money at it, except maybe on the East coast. To really have fun with a regional strategy I would think you need enough routes to support at least 20-30 a/c. My opinion, anyway.
