Mark Dunkerley is most happy when he's flying an airplane – upside down. The Hawaiian Airlines President and CEO grew up with aviation fuel in his blood, flying unaccompanied between boarding school in London and his parent's home in Washington D.C., and eventually earned a degree in Air Transport Economics. Since 2002, Dunkerley has been at the helm of Hawaiian Airlines. And his passion for flying upside down? That kicks in when Dunkerley is piloting his personal aerobatic aircraft.
