NEW RULES FOR TRAVELERS

Changes are afoot for domestic flights-and for some international trips, too.

TRAVELING soon? If you haven't been to an airport lately, now's a good time to brush up on some recent developments that will affect you in the security line. And if you're planning a trip across the pond, you may have to get a special authorization to enter the country you're visiting.

REAL ID. For adults who board domestic flights, the Transportation Security Administration now accepts only a driver's license or other state-issued photo identification that is compliant with REAL ID security standards. The rule, which went into effect in early May, stems from the REAL ID Act, a 2005 law that established minimum security standards for state licenses and other IDs.

If you don’t have a REAL ID, you can get one by going to a branch of your state’s department of motor vehicles and presenting documentation such as your birth certificate, Social Security card and proof of address. (You can find the requirements of your state at the website of its driver’s licensing agency, which you can look up at usa.gov/state-motor-vehicle-services.)
