The TSA's goal is to lift the restrictions on carrying liquids, aerosols, and gels aboard aircraft. Toward that end, the TSA has been rolling out new luggage screening machines that can tell the difference between a harmless drink and a deadly explosive. Already, about 500 of these AT X-ray machines have been installed. That number should be doubled by year-end.
By fall 2009, the TSA hopes to get rid of its rule that you must carry all of your liquids in a single clear bag. For a brief period, you'll probably still have to place all of your liquids in a plastic bin separate from your laptop and carry-on bag when passing through airport screening machines.
By next winter, the TSA hopes to lift its size restrictions on liquids, which now limit the carry-on size to 3.4 liquid ounces. The timetable depends on how quickly software updates can be installed on all of the machines and how quickly TSA agents can be trained to use the machines correctly. Officials with the British counterpart to the TSA, the transport ministry, have made a similar pledge.
