Magoon became president and chairman of Hawaiian in 1964 after gaining majority ownership from Honolulu financier Harry Weinberg. He remained president for about 18 years and continued as chairman until 1989.

To Hawaiian Airlines, Magoon was a "friend and father figure to many in our company," helping shape the airline over one-third of its 74-year history, according to a written statement from the company.

"It is with deep sadness that the Hawaiian Airlines 'ohana learned of the passing of Jack Magoon today," the company said. "Under his guidance, Hawaiian spread its wings across the Pacific and became an increasingly important player in Hawai'i's tourism-based economy.

"Perhaps more than any other individual, Mr. Magoon defined Hawaiian as an airline distinct in the world by the character of its people."

During his tenure, Hawaiian expanded beyond its role as an interisland airline and started flying to the Mainland.

It became a subsidiary of HAL Inc., and in 1987 developer Christopher Hemmeter offered to buy the company for $100 million, or $50 per share, but he pulled back after the October 1987 stock market crash. In 1989, Peter Ueberroth and J. Thomas Talbot led a group acquiring a controlling interest in Hawaiian.

In a previous interview, Magoon noted the airline's gross revenue increased from $5 million to $375 million while he was chairman, though it also went through periods of losses.

Magoon was born in Honolulu on Dec. 2, 1915, and went to Punahou School, graduating in 1933. He lived near Diamond Head with his wife at the time of his death.

Family members said he will be remembered for his long tenure and influence at Hawaiian and for his trademark attire.

"He was known for wearing his seersucker suit," said son-in-law Peter Dudgeon. "He had five or six."

At various times, Magoon was on the board of directors of family real estate investment firms Magoon Estate Ltd. and Magoon Brothers Ltd., his own real estate holding company Hawaiian Securities & Realty, as well as Hawaiian Trust Co. Ltd. and First Insurance Co. of Hawaii Ltd.

He was a board member of Kapi'olani Medical Center, landowner Castle & Cooke and other organizations.

Before buying a majority interest in Hawaiian Airlines, Magoon ran a laundry business in Hawai'i. He also invested in a laundry business and bowling alley on Maui. After leaving Hawaiian, he invested in Coffees of Hawaii Inc. on Moloka'i.

He is survived by wife, Jeanette; daughter, Sara Dudgeon; son-in-law, Peter Dudgeon; grandchildren Shawn Badham, Shannon Piper and Andrew Dudgeon; and five great-grandchildren.
