This sucks in that they are cutting services, though it doesn't really affect me much as I rarely fly the transcon routes.

Any word on the effective date for this change?

And really how many destinations are affected? I count four from memory (SAN, SNA, SEA, PDX) for a total of 12 flights each way daily (3 to each destination). LAX/SFO offer a combined 13 flights each way daily, so the majority of the transcon flights will keep the service, if you want to twist the stats that way.
