Yes. I travel to Asia 3 times a year. After getting over my initial paranoia of going thru security, I now smoke up before every trip. On my last trip, I arrived to find the fight delayed by three hours. I checked in my bags, got my boarding pass and took the Airtrain back to Penn Station (I live 3 blocks from Penn). I re-fired and made it back to Newark on the last Air-train. Boarded the plane 30 minutes later and was feeling happy through the re-fueling in Seattle. Wish I could have re-fueled in Seattle also. Wore off about mid-way to Taipei. Highly recommend.
