Yes, PLEVO is safe to travel all over the World in ANY Airline. We know this because the regulation around "smart luggage" talks about built-in batteries, and as PLEVO's battery pack is removable, there is nothing to worry about. We made sure to make all our components compliant with all Airlines Regulation bodies (IATA, EASA, TSA, FAA, etc.) and we contacted them to re-confirm that we are compliant. We also had the same communication with individual Airlines and all gave us the green light about how we built our product. We are proud to say we are the firs Smart Luggage that is safe to travel Worldwide!
