Set up a solid out-of-office message. Do this early, so that you’re not stressing about typing it out before heading to the airport. You can say, “I’m out of the office until (enter date). Try me then.” Short, to the point, and this clarifies that you will not be available or responsive until after a certain time.
Use airplane mode, even after landing. Many people suggest swiping that airplane icon up whenever you can. Airplane mode doesn’t allow accessing the internet for everything you need, but it does put an end to alerts, in case you didn’t have the strength to disable alerts. Airplane mode at least keeps your phone somewhat muted, and again, connecting requires you to stop and think whether you really need to look at your phone.
Get a real camera. If you can, bring along a real camera. That’s right, one of the old-school versions that’s separate from your phone. Taking a photo is often why we reach for our smartphone, which too easily translates to just refreshing a website or checking in with a text. Save yourself the need to reach for your phone, and instead simply capture the moment. Maybe even reach for nothing, and enjoy the view.
