Posts concerning Frontier passengers raise suspicions about impersonation emails using booking information. The airline’s official notice confirms an active phishing campaign involving reservation revalidation, payment updates, and refunds, but does not confirm a new breach or its scope. Avoid links and attachments in suspicious messages and check bookings by entering the official address yourself or using the official app. Anyone who has supplied payment details should contact their card issuer. Passenger reports and the airline’s confirmed phishing warning are different levels of evidence.
