Southwest Airlines is implementing a new safety policy, effective May 28, requiring passengers to keep portable phone chargers and power banks visible during flights when you're charging a device. The airline will prohibit the use of these devices while they're stored in carry-on bags or overhead bins,

Passengers on Southwest Airlines flights will soon be required to keep their portable chargers in plain sight while using them because of concerns about the growing number of lithium battery fires.

As of May 28, Southwest Airlines’ new charger policy is in effect. The change comes after multiple safety incidents and dozens of recalls involving overheating or exploding chargers, according to Travel and Leisure.
