Look at the large base openings, closings, vacancies, and displacements in the last 18 months alone. The truly scary thing is that these were on stagnant fleets. If they can't manage stagnation without catastrophic financial mistakes, how in the world would anyone surmise that they will have the ability to manage the massive downsizing of one fleet, and the growth of another?

The chance of them getting it right is less than zero.

For insight into the possibilities, I would recommend paying attention to UAL during the next week as they try to accomplish combined CMS and FAR 117 simultaneously. Grab some popcorn and your favorite beverage, sit back, and get ready for some serious entertainment.
