We announce the passing of Lt. Cmdr. Mark “Gucci” Dunleavy, a beloved American aviator and a cherished figure in the military and aviation community. Mark passed away on Friday, July 11, 2025, after a courageous battle with glioblastoma. He was a man of unmatched skill, quiet strength, and unwavering honor.
A distinguished Naval Aviator, Blue Angels demonstration pilot, Top Gun graduate, and JetBlue Captain, Mark’s career was a testament to excellence, discipline, and grace under pressure. Whether soaring in formation with the elite Blue Angels or guiding commercial flights with calm professionalism, he earned the admiration and respect of all who knew him.
To his peers, he was known simply as “Gucci”—a call sign that captured both his cool confidence and his polished, precise approach to aviation. But beyond the cockpit, Mark was even more: a devoted family man, a loyal friend, and a mentor to countless fellow aviators.
Those fortunate enough to serve with or fly alongside him speak not just of his talent, but of his kindness, humility, and genuine warmth. Mark treated everyone with respect, led by quiet example, and carried himself with dignity that never demanded attention, yet always earned it.
His passing leaves an immeasurable void within the military aviation community, among his JetBlue family, and across the many lives he touched with his mentorship and camaraderie. He was the embodiment of a life lived with honor, purpose, and heart.
The Dunleavy family asks for privacy during this difficult time and extends their gratitude for the outpouring of love and support.
As we honor his memory, we hold close the image of “Gucci” in the skies—soaring with precision, strength, and grace. His legacy is not only in the flight paths he carved through the air, but in the spirit of excellence and kindness he left behind on the ground.
Blue skies and tailwinds forever, Gucci.
