I was at SEA early one Sunday morning to try and catch a shot of Salmon Thirty Salmon before it was repainted.  Northern Air Cargo also departs at a similar time of day as part of its loop between Hawaii, Seattle, Los Angeles and back to Hawaii.  I assume one of the regular jets was in maintenance because they had chartered in some capacity from StratAir.  I was not familiar with this operator but I was happy to catch a 767 in new colors for me.
