JetBlue Airways faced significant leadership challenges as it rapidly expanded, hiring many crewmembers without supervisory experience, which led to a decline in the organizational culture. To address this, JetBlue developed a comprehensive leadership training program, Principles of Leadership (POL), emphasizing five core principles and utilizing the Denison Leadership Development Survey for feedback and assessment. The airline's commitment to cultivating effective leaders is aimed at maintaining its unique customer experience and organizational culture amid growth.
