JetBlue Airways Corp. announced it has named Joanna Geraghty to president and chief operating officer, along with other changes to the company’s senior leadership in the coming weeks designed to enhance day-to-day operations and better support execution of its longer term strategic initiatives.

Geraghty will report to Robin Hayes, who will remain chief executive officer and who will continue to oversee the company’s long-term strategy, its structural cost program and efforts to achieve superior margins, and its focus on expanding and evolving into new businesses such as JetBlue Travel Products. Geraghty will manage the day-to-day airline operation, focusing on efforts to deliver a leading customer service experience, execute key structural cost initiatives and enhance operational performance. She will also oversee JetBlue’s commercial team, led by Marty St. George, JetBlue’s executive vice president, commercial and planning.

Geraghty joined JetBlue in 2005 and was most recently executive vice president, customer experience, responsible for delivering the JetBlue experience to millions of customers annually through her leadership of 15,000 customer-facing crewmembers. She served as executive vice president, chief people officer from 2010-2014 and was previously the airline’s vice president and associate general counsel and director of litigation and regulatory affairs. Geraghty is president of the JetBlue Foundation and chairperson of the board of Concern Worldwide, an international not for profit. Prior to joining JetBlue she was a partner at a New York law firm.

“JetBlue has succeeded in this incredibly competitive industry with an unwavering commitment to our crewmembers and our customers, both of which fuel shareholder value. We first disrupted this industry nearly 20 years ago and we will continue to do so,” said Hayes. “This new structure will allow focus on the core airline business while providing an organizational structure to innovate and grow in the travel and vacations space. Joanna has played an important role in JetBlue, and I look forward to working closely with her for many years to come.”

“I’m honored and humbled to take on this role and I am committed to supporting our nearly 22,000 crewmembers at JetBlue as we continue to prove why we are the airline that inspires humanity,” said Geraghty. “We believe we can be a great business for our owners, a great place to work for our crewmembers, and the best airline for customers. Our passion for the crewmember and customer experience, combined with our commitment to low costs, makes us a unique player in the industry with a lot of runway ahead.”

Geraghty received her undergraduate degree from the College of the Holy Cross and her master’s in international relations and juris doctor from Syracuse University.

Jeff Martin, currently executive vice president, operations, will take on a senior advisor role for JetBlue to ensure a smooth transition following this reorganization.

“I’d like to thank Jeff for his many years of service to JetBlue,” Hayes said. “Jeff has done an incredible job leading the safe and secure operation of the airline while helping evolve our fleet, invest in Tech Ops, and position us as a leader in NextGen. He has made a big mark on JetBlue and in particular I want to thank him for being a true champion as we transitioned to working with ALPA and secured our first pilot agreement.”
