The TSA is considering allowing passengers with TSA Precheck to bring water bottles through security at airports that have the most advanced scanners.
They did not say when this might happen or which airports. They did say it does not mean they are eliminating the need for 3-1-1 bags or the limit of 100ml/3.4 oz of other liquids.
It should be noted that TSA reports that over 20 million people have TSA Precheck.
The new scanners are capable of identifying water versus other liquids.
