In 2010, airlines worldwide lost an estimated USD1.4 billion  in revenue due to online fraud perpetrated on their websites, which represented 0.9% of total worldwide online airline ticket sales. In comparison, airlines reported losing USD 1.7 billion in the previous survey2, representing 1.3% of total online airline ticket sales worldwide. This represents a 31% reduction in fraud loss rate from what was reported in the previous survey. However, over a quarter of airlines surveyed expected their fraud loss rate to be greater than 1% of their online revenue in 2010, suggesting there are still some airlines that could improve their online fraud management processes.
