Frontier Airlines site leaks all personal info with just a glance at a boarding pass, researcher claims — booking number and last name nets you every passenger's personal info, including address, passport, TSA PreCheck, and most credit card info
⚡ Quick Hits
- Just a last name and a booking number are enough to access a passenger's complete Frontier Airlines profile.

Greetings, travelers and tech enthusiasts! The Tech Monk is here with an urgent security alert. While my usual mission is to curate the ultimate tech deals, today we are dealing with a massive privacy "dealbreaker" that you need to know about before your next flight.
According to a disturbing claim from a security researcher, Frontier Airlines is currently dealing with a catastrophic privacy flaw on its website.
The Vulnerability Explained
Have you ever posted an airport selfie featuring your printed ticket? You might want to think twice. Researchers have discovered that anyone with a quick glance at your boarding pass can hijack your personal data. All a bad actor needs is your last name and your booking number.
By simply plugging these two readily available details into the Frontier booking portal, unauthorized users are granted full access to the passenger's backend itinerary and profile.
What's on the Line?
The sheer amount of Personally Identifiable Information (PII) leaked by this exploit is staggering. A quick entry of the booking details nets an attacker:
- Full home addresses
- Passport information
- TSA PreCheck numbers
- Most of the passenger's stored credit card information
The Tech Monk's Advice
Treat your boarding pass like a highly sensitive document. Never leave it behind in the seatback pocket, avoid tossing it in public airport trash cans without shredding it first, and absolutely never share photos of its barcode or text on social media. Stay safe out there!
