A screenshot of a boarding pass is usually sufficient for passing through security and boarding your flight in 2026, but it is considered a "backup" rather than the ideal method. TSA agents and airline gate readers only need to scan the QR code or Aztec code to verify your details. However, there are several downsides to relying on a screenshot. First, a static image does not update; if your gate changes or your flight is delayed, a screenshot won't show the new information, whereas the live pass in your Apple or Google Wallet will update automatically. Second, if your screen is cracked or the brightness is too low, the scanners may struggle to read the image. Third, some international airports and specific airlines require the "live" pass within their official app to verify real-time security clearances. It is always a best practice to add the boarding pass to your phone's digital wallet, which works offline and even when your battery is very low. If you choose to use a screenshot, make sure the entire barcode is visible and that your screen brightness is turned up to 100% when you approach the scanner to avoid holding up the line.
