Jim Dunn, owner of the Airtel Plaza Hotel in Van Nuys, died Monday of health care complications. He was 70. In addition to running his hotel, Dunn served on the board of the Valley Economic Alliance and as co-chair of the Aviation Policy Committee for the Valley Industry & Commerce Association. A former fixed-wing and helicopter pilot, Dunn melded his love for aviation with his love for the hospitality industry by opening a hotel adjacent to the Van Nuys Airport. He hosted many community events at his hotel and was involved in airport policy issues.
