Frontier Airlines has warned customers about an active email phishing campaign. According to NBC Philadelphia, the emails offer refunds or claim there is a problem with a payment, and ask for bank or card details. Some reportedly include real passenger names and booking codes. Frontier says it never asks for payment details by email.
Two versions of the bait. According to travel blog Live and Let's Fly, which cites a report from View From The Wing, one version promises a refund once the passenger verifies the card used for the booking. Another says that payment for an upcoming trip has not gone through. That creates urgency for anyone about to fly. Some passengers report that they entered their card details on the linked websites.
Real data, fake emails. The most worrying detail, according to Live and Let's Fly, is that passengers say the messages contain genuine confirmation numbers and flight details. Frontier's own warning does not mention this. It confirms only that an active campaign is targeting its customers.
What Frontier says. On its phishing awareness page, the airline states that it does not email customers asking for flight, reservation, payment or contact details. It will never ask passengers to revalidate a reservation, re-enter card information, provide payment details to receive a refund, or click a link to confirm card, billing or refund details.
Why it matters
The source is unclear. It is not known how the scammers obtained the reservation data. Live and Let's Fly lists several possibilities, including a breach at the airline or a supplier, compromised credentials, insider misuse or hacked passenger email accounts. The blog says there is not enough evidence to identify the source. It also notes that Frontier disclosed a security incident on October 2, 2026, involving its customer care database and its customer care form. Frontier said it updated the database configuration and improved monitoring after that incident. The blog stresses that this does not establish any link to the phishing campaign.
- Do not click links or buttons in suspicious emails, and do not reply to them.
- Check your reservation by opening Frontier's official website or app yourself.
- A correct confirmation number does not make an email legitimate.
- If you already shared card details, contact your card issuer or bank.
- For questions, Frontier lists the phone number 801-401-9000.
The takeaway. Live and Let's Fly argues that passengers should not carry the whole burden of spotting convincing fraud. It says Frontier should explain, as far as its investigation allows, how scammers got the information that makes these messages so believable.
