Herb Kelleher was the longest serving CEO in the airline industry. A charismatic leader, highly popular with managers, employees and the press, he created a unique culture and leadership style at Southwest Airlines. As he approached retirement, there was much anxiety among Wall Street analysts, other industry observers and employees about how Southwest Airlines would fare following his departure in 2001. We examine the successful change in leadership at Southwest Airlines over the last few years and highlight the contributing factors that led to a seamless transition.

Southwest Airlines is a remarkable company. It has sustained a steady 10–15% rate of growth over the last 30 years and turned a profit in every year after its first. In an industry that regularly loses billions of dollars, this is quite extraordinary.

Ability to Build and Maintain Quality Relationships

Jody Gittell[1] conducted field research into the airline industry over a period of eight years. Gittell concluded that Southwest Airline’s most distinctive characteristic is its ability to build and maintain quality relationships among managers, employees, business partners, unions and suppliers. These relationships are based on:

  • shared goals
  • shared knowledge
  • mutual respect

The quality of these relationships provide the foundation for competitive advantage, through good times and bad, and is widely regarded as the most essential factor contributing to Southwest’s success.
