Heads up, frequent flyers: Southwest just made a new rule—no more using your power bank while it’s stashed in your bag or the overhead bin. Turns out, lithium batteries can get a little too hot to handle, and if your charger starts smoking, the crew needs to spot it fast. So, if you want to juice up your phone mid-flight, keep your power bank out in the open. It’s a small change, but it could save your trip (and everyone else’s)! #TravelTips #FlightHacks #SouthwestAirlines #SafetyFirst #MoneyLifehacks #Business
