Why can’t I add the Aitbnb pass to wallet?

Hey there quang104,

Thanks for reaching out in Apple Support Communities. I understand you’re having issues adding your Airbnb pass to wallet. I’ll be happy to help with this.

"You can add passes to Wallet in several ways:

• Using Wallet-enabled apps (Scroll down in Wallet, tap Edit Passes, and tap Find Apps for Wallet.)
• Scanning a barcode or QR code (Scroll down in Wallet, tap Edit Passes, tap Scan Code, and use your iPhone camera to scan.)
• Tapping a Wallet notification that you got after paying with Apple Pay at a supported merchant
• With Mail or Messages
• Through a web browser
• Sharing through AirDrop
• From your Mac
• Creating an iTunes Pass
• For student ID cards, using the eAccounts app

If you don't see the option to add a card, ticket, or other service to Wallet, contact the merchant to make sure that they support Wallet passes.

You may need to tap Add to Apple Wallet and then tap Add in the upper right corner of the pass. Or you may see a popup with an Add button you can tap to add your pass to Wallet."
