Yes, Flyte is safe to fly with. Flyte has a lithium ion battery that is contained within the unit and can’t be removed from the device. As with other similar devices, the Federal Aviation Administration (FAA) prefers to have it in carry-on baggage, but you can also have it as part of your checked baggage, just be sure Flyte is off. Per the FAA, “Devices containing lithium metal batteries or lithium ion batteries, including – but not limited to – smartphones, tablets, cameras and laptops, should be kept in carry-on baggage. If these devices are packed in checked baggage, they should be turned completely off, protected from accidental activation and packed so they are protected from damage.” Lithium Batteries in Baggage | Federal Aviation Administration (faa.gov)
