The answer is YES! The TSA do have plans to increase the size of the liquids you can take on an airplane! This is because of the scanners being rolled out in airports across America, but it will take 16 YEARS before they are fully deployed in airports and ready to use.
The new size would be about 68 ounces, but the roll-out of the new scanners is slow, and the TSA expects that it will take until the year 2040 to upgrade all 2,000 screening lanes in about 430 airports across the U.S.
Something to look forward to!
