N7860A (c/n 29362, l/n 1713), a former China Eastern Airlines 737-79P, is ferrying to PAE from KMG [Changshui International Airport, Kunming, China], via GUM and HNL. It's owned by AerCap, and will be leased to Southwest Airlines.
29362 was delivered to China Eastern in May 2005 as B-5096. It was fitted with Blended Winglets in late 2011, along with the green peacock feather. In February 2014, it was painted in the orange Yunnan Peacock livery; and three months later, it was sold to AerCap, and leased back. B-5096 was withdrawn from service this past April.
