Looks like DL believes it needs to provide flights under its own control to feed its growing int'l operation at SEA (up to 8 destinations by next summer) with the addition of SEA-SFO flights. SEA-SFO flights will be operated up to 7X/day on E175s. This past summer, DL added SEA-LAX on its own aircraft and currently has a mix of DCI and DL operated flights. SEA-LAS was also operated 1X/day this summer on a DL aircraft and is being expanded to multiple frequencies per day on large RJs. Interestingly, UA just noted that its RASM growth on int'l routes was weaker than expected due in part to increased industry capacity to China. DL and several Chinese airlines have added more than 50% more seats between the US and China over the past year.
