Q. I know that the TSA limits liquids and gels in your carry on bags to three ounces each, but is there a limit to how many such items you can carry on board?
A. Actually, the official limit is 3.4 ounces, or 100 ml. You may carry as many containers as will fit in a one-quart clear plastic "zip" bag. More information at http://www.tsa.gov/311. By the way, several websites specialize in a wide range of TSA-approved travel sized products, many of them impossible to find at your local drug store, including www.3floz.com and www.traveltoiletrykits.com.
