Your mobile boarding pass should always be a tap or two away from your home screen. You’ve got a link to it in your email or your texts, or you’re sure you put it into Apple Wallet. But should isn’t always good enough when you get up to the TSA desk and the airport’s wifi is flaking out. Always take a screenshot.
Screenshotting everything is an indispensable travel hack. (On iPhone, hold down the power and home buttons at the same time; on Android, it’s usually the power and volume-down buttons.) This way, the information you should have available will always be in your photos app. That said, your photos aren’t super private, say if you were to hand your phone over to somebody, so consider whether you want to keep that information in your camera roll long-term.
