Recent controversy settled. Per this tweet from TSA, peanut butter is a liquid. Who knew?
(FWIW - some of the TSA tweets are pretty funny, and tend to be full of travel tips!)
You may not be nuts about it, but TSA considers your PB a liquid. In carry-on, it needs to be 3.4oz or less. Make sure all your travel-sized liquids fit in one quart-sized bag. #PeanutButter pic.twitter.com/4RzDv3Up7B
