Despite reporting a recent “pronounced upswing” in business jet charter business in the Gulf Cooperation Council territories, Middle East charter and aircraft management firm Rizon is rationalizing its activity in the area to cut costs. Rizon attributes an increased market share to recent introduction of a charter Bombardier Challenger 605 at Qatari capital city Doha, to which the company is also moving its Bahrain headquarters back-office and administrative functions. “The move will enable us to reduce costs by 15 to 20 percent, while improving administrative efficiency,” according to Rizon, which is reducing its Bahrain and Sharjah, UAE offices to sales and marketing activities. Rizon is building a 20,000-sq-ft hangar and FBO at Doha Airport that is scheduled to open in March 2010. It has received a Qatar air operating permit that is said to be the first issued to a Doha-based private jet company for “dedicated business jet operations from Qatar.” The operator said “many” of its Bahrain and Sharjah staff are moving to Doha.
