Maybe no connection here, but tonight we saw a 737 in MSP (US) with a "Euro" flag (dark blue with a circle of stars) and what appeared to be a small Dutch flag, both near the left rear exit. And the plane had a good bit of green paint on both sides of the fuselage, with the name 'Sun Country' on it. Sun Country Airlines has been based for years in MSP, but most of their 737s seem to have the purple and orange colors.
