What to expect now at the airport security line?
• The rules you may have heard about recently—such as being required to sit for the last hour of an international flight—are no longer in effect. Flights have returned to normal, by and large. The routine of airport screening—you know, slip off your shoes, take your notebook out of your bag and put it on the conveyor belt in a bin—remains the same. Some differences:
• U.S. citizens flying domestically may be selected at random for additional screening.
• U.S. citizens flying internationally may be selected at random for additional screening that may include some mix of a full-body pat-down, a whole-body scan, and an inspection of carry-on luggage by hand and with the use of explosives-detection technology.
• The number and type of allowed carry-on items is still the same.
• "Passengers should not expect to see the same thing at every airport," the TSA says on its website. Citizens of foreign countries may be subject to heightened security attention at foreign airports or on entry into the U.S. Or they may not, depending on local policies. Citizens of, or travelers to, the following countries, may receive the most attention Afghanistan, Algeria, Iraq, Lebanon, Libya, Nigeria, Pakistan, Saudi Arabia, Somalia, or Yemen, as well as Cuba, Iran, Sudan, and Syria.
