I flew last week Seattle-Laguardia and back and had no questions at all. I had an E2e with scalloped KL1, the E2e incandescent head, and spare CR123s. Also had a PT Attitude, digital camera with 4 AA NiMH with 8 spares, electric razor, etc. Not a peep, which surprised me with recent news about TSA being on the lookout for bombs disguised as batteries. I was careful to check the allowed/not allowed list at the TSA (nail clippers ARE allowed now) and remove any tools and blades.
