Airlines need to proactively monitor their loyal shoppers' membership accounts since the problem of loyalty fraud is on the rise. If on one hand airlines are offering more earning and redemption choices than ever, it also means that the overall loyalty earning and burning lifecycle has opened new avenues for fraud. "From a loyalty fraud standpoint, there is a lot of demand (for stolen loyalty currency among the fraudsters or in a marketplace on the dark web)," says Kevin Lee, Trust & Safety Architect, Sift. This is because over a period of time, prices for such items (stolen credentials, miles, points etc.) even though they fluctuate a bit still they are going up in value. Data breaches are a big issue, and a lot of sensitive information is being sold.
