Blue Flat
Why Southwest Airlines 737 have a bright (bright) blue paint and some other flat blue 737??
Is it because the bright blue fades with time or is the bright blue is the new way of painting in the southwest 737??
They changed paint schemes and just wait until the A / C gets into Heavy maintenance painting. Not too many airlines can afford to pull a flying machine hours for painting only
