Singapore Airlines has been taking delivery of a bunch of 737 Max8 jets.  These were bought by the Silk Air subsidiary but, after the order was place, Singapore decided to integrate that subsidiary into the main airline.  Plenty of the aircraft had been painted before this decision was made and I guess Boeing’s price to repaint the jets was higher than the other options available so they were delivered in the old colors and then repainted after delivery.  However, more recent jets have been painted in Singapore’s colors from new.  737 deliveries usually happen from Boeing Field but, for some reason, this jet was delivered from Paine Field.  The sun popped out as it lined up to depart for Hawaii where it would stop en route.  Not often you get an airline flight between Paine Field and Hawaii!
