I know there has been a lot of discussion on this topic recently but I find I am still a bit confused about the requirements. My wife and I are traveling to South America next week and I'd like to be prepared. We have Global Entry, which includes TSA precheck, so I don't think we'll be required to remove the cameras from their bags. I understand that all batteries must be in carry-on luggage. Has anyone flown recently who can confirm my understanding?
