That globe will still be featured on each aircraft’s tail, but in sky blue rather than gold. The tail itself will incorporate three different shades of blue. Engines and wingtips will also be blue, as will the formerly gold line running across the aircraft’s main body. The line will also have more of a swoop than the current design — meant to signify a “more nimble, flexible company,” Krolick said. The swooping line already appears on United’s Boeing 787 Dreamliner aircraft.
