JetBlue has been sued in a proposed class action claiming it uses customers’ personal data to set ticket prices, after its response to a social media post raised concern that the carrier employed “surveillance pricing” to make flying more expensive.

According to a complaint filed late on Wednesday in Brooklyn federal court, JetBlue conceals its use of “trackers” to set prices dynamically, and shares data with third parties whose programs help it decide when to raise fares.
