When Alaska Air Group finalized its acquisition of Hawaiian Airlines, it not only inherited a highly recognizable brand, but also a complex fleet that mixes both Boeing and Airbus aircraft. The newly combined carrier now operates the Boeing 717, 737, 787 Dreamliner, Airbus A321neo, A330-200, and Embraer E175, a stark contrast to its sole 737 mainline and E175 regional fleet just two years ago.
