Trying to stay current these days on the do’s and don’ts of air travel can trip up even the most experienced traveler.

U.S. military officials in Europe and the United States encourage Defense Department personnel on this side of the Atlantic to routinely check for changes in policy. The Transportation Security Administration,, sets such policies for the Department of Homeland Security.

Even the Air Force’s Air Mobility Command is following the TSA’s lead.

“All of the TSA standards are being implemented at our AMC terminals,” said Angel Lopez, a spokeswoman for AMC headquarters at Scott Air Force Base, Ill.

Those adjustments were made last week. But in the current environment, guidelines and policies can change overnight.

ItalyENAC, Italy’s authority for the security of airlines, issued a bulletin Monday that banned liquids, gels or sprays from flights bound for the United Kingdom, United States and Israel.

Medications and food for children are exempt, but must be tested before permitted beyond the security gates.

Travelers from Italy bound for one of those three countries can carry gel or aerosol products only if bought in the commercial areas past the security check, said Luigi Irdi, a spokesman for Italy’s Ministry of Transportation.

These rules are in effect until Aug. 31, when ENAC officials will revisit the restrictions and determine if they should remain in place.

Such restrictions have not been imposed on flights bound to other parts of the world. However, Italian airport officials tightened security restrictions and are conducting random, manual inspections of some travelers’ carry-on luggage.
