To "scan" a plane ticket onto your iPhone in 2026, you generally use the Apple Wallet app rather than a traditional scanner. When you check in via your airline's app or website, look for the button that says "Add to Apple Wallet." Once you tap this, your boarding pass with its QR code is saved to your device. You can access it by double-clicking the side button (on FaceID phones) or through the Wallet app. If you have a physical paper ticket, you cannot usually "scan" it into the Wallet app manually for security reasons; instead, you can take a photo of it for your records or use the airline's app to "scan" the confirmation number, which then generates a digital version you can add to your Wallet.
