TSA Uses New CT

Here’s some good news for travelers.


The TSA has started to use new CT, or computed tomography scanning devices, for carry-on bags which are better at detecting explosives and other threats.


The machines are now at more than 228 US airports. They create impressive 3D images of a bag’s contents, allowing for more thorough inspections on the screen and fewer physical bag searches.


But for the moment, you may be waiting longer in security lines. Why? The TSA now has to train its officers on the machines.
My advice is that when picking a security line, look for just one TSA agent monitoring the screen at the conveyor belt. If there are two officers looking at that screen, that means that one of them is in training, and you’ll be waiting as each bag is stopped for longer periods of time.
