Didn't go through the South. Connected in SFO and EWR from SEA. All legs late. Good weather too, except for rain in SEA. The strangest reason for a delay was SFO-EWR - they said they discovered something on the airplane and needed to clean the aircraft again - flight delayed by more than an hour. Not sure what kind of cleaning they were doing, because it's not like the plane was super clean when we boarded.
