Hi there! I'm John Nguyen, and I'm here to help you with the issue you're experiencing with the Virgin Atlantic app not locating your boarding pass. Let's work through this together!

First, could you let me know if you've already checked in? Sometimes, the boarding pass might not appear if the check-in process hasn't been completed.

If you have checked in, let's try these steps:

1. Refresh the App: Close the Virgin Atlantic app completely and then reopen it. This helps refresh all the information.

2. Check Your Booking: Go to the 'My Bookings' section in the app or on the website. You should be able to access your boarding pass from there. You can visit this link to retrieve your booking for reference.

3. Internet Connection: Make sure you have a stable internet connection. Sometimes, connectivity issues can prevent the app from retrieving your boarding pass.

4. Update the App: Ensure you have the latest version of the Virgin Atlantic app installed on your iPhone. You can check for updates in the App Store.

5. Check in via Website: If the app is still not working, you can check in through the Virgin Atlantic website and download your boarding pass from there.

If you've tried these steps and the boarding pass is still not visible, please let me know! We can explore further options or check if there's a temporary issue with the app itself.
