Using European adapters for loose airplane outlets
One minor travel annoyance I’ve regularly encountered is that airplane outlets don’t hold U.S.-style power plugs (types A/B) snugly. My devices come unplugged frequently during a flight. This is especially frustrating to manage in the awkward under seat area.

While taking a couple trips to Europe this past year, I noticed that airplane outlets are international and found that type C/E/F plugs (used in a number of European countries and beyond) fit more snugly and hold for the entire flight.

Since I’m almost always charging USB-powered devices and modern international adapters often include USB ports, I don’t even have to use an additional adapter, just a different one.

I now pack an international adapter whenever I fly, even if I’m traveling domestically.
