I agree that there is a trade off between economies of scale with a huge number of Lear 60XRs and the need to appease the requests for greater/smaller capacity from owners and card holders.

I agree that more details would be nice. Do people have more specifics on hiring plans, pilot bases, actual start-up date, etc.?
