Probably not for quite some time - maybe a couple years down the road. Before that happens, they'd need to start flying a fair number intercontinental routes from these cities - then you'd maybe start to see some transcon domestic runs show up as part of the rotation. But for now, all the flights are ex-DTW, with a later ex-ATL flight planned.

If you started seeing intercontinental flights using A350 and refurbished 777s from LAX,SEA, and JFK, then you might see some domestic flights with them. But that's likely a long ways off.
