JetBlue Airways is embroiled in a proposed class action lawsuit filed in Brooklyn federal court, alleging that the airline uses customers' personal data to set ticket prices through a practice referred to as 'surveillance pricing.' The complaint, initiated by Andrew Phillips, claims that JetBlue conceals its use of data trackers and shares this information with third parties to determine fare adjustments. The lawsuit was prompted by a social media exchange on April 18, where a passenger expressed frustration over a significant fare increase. JetBlue's response suggested clearing browser cookies, which led to further scrutiny. The airline has since stated that its previous response was incorrect and emphasized that ticket prices can fluctuate based on demand. The lawsuit seeks unspecified damages for violations of federal anti-wiretapping laws and New York state consumer protection laws. This case comes amid growing concerns in Congress about pricing practices in the airline industry, with lawmakers questioning whether airlines use personal data for pricing decisions.
