If you've forgotten your physical Priority Pass card, the most effective fallback is the Priority Pass mobile app. Once you log in, you can access your Digital Membership Card, which features a QR code that most lounges can scan for entry. In 2026, many credit card issuers also integrate this digital card directly into their own banking apps (e.g., the "Travel" or "Benefits" section of the Chase or Amex app). If you haven't registered your account online yet, you can usually do so using your membership number, which is often found on your initial welcome email or your monthly credit card statement. A peer-to-peer "pro-tip": take a screenshot of your QR code before you head to the airport. This ensures you can access the lounge even if the airport Wi-Fi is spotty or if you are in a location with poor cellular service, as the digital card is just as valid as the physical plastic version.
