Yes, you can wear heated base layers on an airplane, but you cannot use the heating function during flight. The lithium-ion batteries must be carried in your carry-on luggage (never checked baggage) per FAA regulations. Some airlines may have specific policies, so check before flying. The batteries are typically under the 100Wh limit for carry-on lithium batteries.
