The Singapore Airlines (SIA) originated as a small regional airline with a modest fleet comprising 10 aircraft, a staff of 6,000 and a route network spanning 22 cities in 18 countries about 25 years ago. It began to expand and modernize its fleet, setting standards of service and quality that others could only follow. Well-perceived planning, investment and product innovation boosted its growing reputation and profitability, turning into a world-class carrier today. Their route network has expanded to 90 different cities in 40 countries and modern fleets of aircraft to ensure the safety of their passengers.
