VPNs don't reliably lower flight prices, and using one risks canceled tickets

Using a VPN to find cheaper flights does not appear to work, as airlines have implemented measures to prevent location-based price discrimination. Testing across multiple flight search engines showed prices remained largely the same whether a VPN was used or not, with potential risks of flagged purchases. Airlines and banks can detect VPN usage, leading to canceled tickets, and other tracking methods like cookies and GPS can still reveal a user's true location.
