WestJet, an Alberta Partnership, notified the NH Attorney General of a cybersecurity incident affecting 289 New Hampshire residents. On June 13, 2025, WestJet identified suspicious activity and determined a sophisticated criminal third party gained unauthorized access to its systems.

Credit card numbers and passwords were not compromised. WestJet engaged forensic experts, secured its environment, and reported the incident to the FBI. The incident is now resolved. WestJet is offering 24 months of complimentary identity theft and monitoring services.
