This is a new one on me, According to the Washington Post you can no longer pack loose lithium batteries in checked luggage.
To help reduce the risk of fires, air travelers will no longer be able to pack loose lithium batteries in checked luggage beginning Jan. 1, the Transportation Department said Friday.
If packed in plastic bags, batteries may be in carryon baggage. The limit is two batteries per passenger.
Mmm so does this mean I am allowed to check a lithium if it is still in its original packaging?
The more they make it more difficult to fly the more I wish the US had a reasonable train system or god forbid actually wanting to drive instead.
