Booking.com still misleading consumers with false '1 room left' claims

Booking.com continues to display misleading scarcity messages on its hotel booking platform, claiming that only one room is left when in fact many more are available. Which? Travel found that five out of ten such claims were inaccurate, with one example showing 34 rooms still available at a London hotel. The Competition and Markets Authority had given Booking.com until 1 September 2019 to change its practices, but the platform has not fully complied. Booking.com says it has worked to implement the commitments agreed with the CMA.

AMS algorithm lacks transparency and may discriminate against job seekers

The Austrian Public Employment Service (AMS) uses an algorithm to classify job seekers into categories A, B, and C, determining their access to benefits and training. Scientists from TU Wien, WU Wien, and University of Vienna have criticised the algorithm for lacking transparency, as only two of 96 model variants have been published. They allege that the system may discriminate against women and people with migration background, and that job seekers are not informed about how the algorithm works or given a chance to appeal.

Trivago loses Australian appeal over misleading hotel rate rankings

The Federal Court of Australia has dismissed Trivago's appeal against a ruling that the online travel company breached Australian consumer law. The court found that Trivago's website used an algorithm that gave prominence to hotels paying higher fees, so the most prominent offers were not always the cheapest for consumers. Consumers may therefore have paid more for rooms, and hotels lost direct bookings. The case returns to the Federal Court for consideration of penalties and other orders sought by the Australian Competition and Consumer Commission.

Allstate's proposed retention model charged big spenders more in Maryland

Allstate proposed an auto insurance rate adjustment plan in Maryland using a retention model algorithm that varied premium changes based on existing premiums. The algorithm would have increased rates up to 20% for customers already paying the highest premiums while capping increases at 5% for others, and would have denied meaningful discounts to thousands owed reductions. The Maryland Insurance Administration rejected the plan as discriminatory, but Allstate claims it was withdrawn and has continued proposing similar models elsewhere. The proposal never took effect in Maryland.

ViaQuatro's facial recognition system in São Paulo metro challenged in court

In April 2018, ViaQuatro installed the Digital Interactive Doors System, developed by AdMobilize, on the São Paulo metro's yellow line. The system used cameras to detect passengers' faces and claimed to infer their emotion, age, and gender in order to target advertisements. The Brazilian Institute of Consumer Protection (IDEC) filed a public civil action alleging that the system violated consumer and data protection laws by processing biometric data without consent and making pseudoscientific and discriminatory inferences. A judge ordered the cameras removed in August 2018, and the case is pending a final ruling.

Airbnb smart-pricing algorithm increased racial revenue gap, study finds

A study by Carnegie Mellon University found that Airbnb's smart-pricing algorithm increased the revenue gap between White and Black hosts, even though it narrowed the gap among hosts who adopted it. The algorithm, which sets daily prices automatically, was adopted by fewer Black hosts, so its suggested prices were closer to the optimum for White hosts. The researchers said the tool could reduce racial disparities only if more Black hosts adopted it.

USPS algorithm RRECS causes pay cuts for two-thirds of rural mail carriers

The United States Postal Service (USPS) implemented a new algorithm, RRECS, to evaluate rural carrier routes and determine pay. Due to flaws in how carriers scanned packages, the algorithm underestimated route times, resulting in pay cuts for 66 per cent of rural carriers, some losing thousands of dollars annually. Carriers report that they were not adequately trained on the system and that the cuts are scheduled to take effect, though they have been postponed multiple times. The USPS stated that the system is the result of a nationally negotiated agreement.

Spanish Supreme Court orders release of BOSCO algorithm code for social electricity bonus

The Spanish NGO Civio won a Supreme Court case forcing the government to release the source code of BOSCO, the algorithm that decides eligibility for the social electricity bonus (bono social eléctrico). Civio had demonstrated in 2019 that BOSCO contained serious errors that denied the benefit to vulnerable people who met the requirements. The government had refused to disclose the code, citing intellectual property. The Supreme Court ruled that transparency must prevail, setting a precedent for public access to automated decision-making systems.
