A state court has dismissed the California Attorney General’s claims that Delta Air Lines Inc. (“Delta”) violated the California Online Privacy Protection Act by failing to have an appropriately posted privacy policy for its mobile application, Bloomberg reports. The California AG sued Delta in December as part of an enforcement campaign that began with the issuance of warning letters to approximately 100 operators of mobile apps, including Delta. According to the Bloomberg report, a basis for the dismissal was the federal Airline Deregulation Act, under which a state “may not enact or enforce a law, regulation, or other provision having the force and effect of law related to a price, route, or service of an air carrier that may provide air transportation under this subpart.” 49 U.S.C. § 41713.
