When I would board planes on airlines like Delta and United during my time with an iPhone, I would load the boarding pass into the Passbook app (which became the Wallet app with iOS 9) and would not have to print out my boarding pass. Now I have an Android phone and a United flight tomorrow. How can I use a United boarding pass digitally on my Nexus 6P? Is there a Passbook-like app for Android or do most airlines support in-app digital boarding passes, so I can board the flight with just the United app and no printed pass maybe?
US domestic flight, if that matters. Android 6.0.1.
