I assume the plan will look something like this.

Leverage size and customer position with Boeing to get an initial batch of 787s (5-10) that will be delivered in a short window in approx 3-5 years. Boeing isn't going to tell the worlds largest operator of Boeing aircraft, exclusive to Boeing for 50+ years, to pound sand.

The initial crews will be domiciled somewhere like DEN (most likely) or BWI and will operate domestically at first to give time for things to be figured out before adding the complexity of international. Think DEN-BWI, DEN-HNL (when ETOPS is approved), DEN-BNA, DEN-MCO, etc. We will have to invent many things here to fly a big plane.

After a period of time has elapsed (maybe 12 months?) international will gradually be added in and more aircraft will come.
