I often get flight or concert tickets that don't come as Wallet entries, but I wan't to treat them in the same way: 1. Easy Access (e.g., not searching back through emails or logging in to a service); 2. Not dependant on internet/phone connectivity (especially in airports!)

I now have a pair of shortcuts that more-or-less achieve this. In operation, I just open my iPhone, tap an app icon (shortcut to 'LocalFileOpener').

How it works:

'→ Local iPhone' Appears in the Share Menu and saves a file locally on my iPhone (i.e., I don't need an internet/phone connection to access it as I would with iCloud storage).

'LocalFileOpener' Just opens the local iPhone folder.
