Picture the scene: You’re on a plane, and your iPhone is your entertainment hub. You may be listening to podcasts, or music, or audiobooks. You may be playing a game, or reading Instapaper, or just checking and editing your vacation photos. Whatever you’re trying to do, it will be interrupted every time you unlock your iPhone, because your stupid boarding pass is right there on the lock screen. Even hours into a transatlantic fight, the boarding pass you already used hangs around, blocking things like the now-playing feature, and lock-screen controls for any music or audio apps.
Thankfully, it’s easy to get rid of — if you know where to look.
