Flown several times with gear and no problems with TSA. I take the equipment with me in my laptop case (with the laptop, kindle, ipod), and a few bottles of liquid in the baggie. I only have to take the laptop out. For bulk liquid I learned to put those inside a larger screwtop water bottle (Nalgene) as it keeps them from leaking in the checked baggage. DO NOT travel with a full clearomizer/tank/RBA/bottle!!! Leave some empty space for head room. Aircraft cabins are pressurized to 8,000ft and the internal pressure inside your tank will push juice out. If you can, try to position the equipment so the wicks are in the air space on takeoff (tip down for BCC's and cartos, tip up for vivi's, CE4's and juice bottles) that reduces the chance of getting a juicy handful of vapegear at your destination. Another trick is to have a gallon ziplock with some vaper towel and put the equip in that before takeoff.
You can't vape on the plane, but you may be able to at airports. I carry some nicotine gum while travelling to handle the cravings that happen. Something about not being able to vape makes the cravings worse for me.
Above all, relax, enjoy your trip.
