The rules state that a passenger may carry on liquids and gels only in separate three-ounce containers in a single quart-size plastic bag, with a limit of one bag for each passenger.
That new X-ray technology may be capable of electronically identifying explosive chemicals, allowing the agency to drop the much-disliked rule that restricts passengers to carrying on liquids or gels solely in containers holding 3.4 ounces or less, packed in a single quart-size zip-top plastic bag.
For the first time since 2001, travelers are going through airport security checkpoints with their shoes and jackets on, and without having to remove laptops from cases or adhere to rules like displaying carry-on liquids in containers of 3.4 ounces maximum, all packed in a single quart-size plastic bag.
In response, officials banned liquids altogether and then, after laboratory testing here and abroad, came up with the formula of limiting liquids and gels to three-ounce containers in a single quart-size bag "as a way to allow for people who wanted to bring liquids on board," Mr. Hawley said.
Airports say they are doing their part to make sure that people know the liquid and gel carry-on rules: containers no larger than three ounces, all tucked into a single quart-size, zip-top, clear plastic bag ready to be placed on the security conveyor belt.
High on the list are the requirement to remove shoes (technology will address that in time, Mr. Hawley said), and the hated, widely ridiculed rule that liquids and gels may be carried onto airplanes only in three-ounce containers contained in a single, quart-sized zip-close bag.
Unless you've never seen the inside of an airport or haven't flown since before 9/11, you likely know the TSA fundamentals and have some understanding of the 3-1-1 rule: Liquids and gels must be in containers of 3.4 ounces or less, and these containers must be in a single quart-size zip-top bag.
Separate three-ounce containers limited in number to what will fit inside a single one-quart bag do not have "enough critical diameter" to blow up an aircraft, he said.
In response to the carry-on rules, which mandate containers of no more than three ounces and require that each passenger's items be placed in a single, clear, quart-size, zip-top plastic bag, some fliers have reverted to old-fashioned hygiene — switching to shaving soap and tooth powder.
He said George T. Lowy, senior counsel at a prominent law firm and a board member of the co-op at 580 Park, a key opponent, had contributed $57,000 to Mr. Rose's most persistent critic, Ms. Krueger, "while I haven't given Quart a single penny".
Clean out a pint-sized jar (for a single serving) or a quart (for a dinner salad).
