With the federalization of airport security, security procedures at U.S. airports are more stable and consistent than ever. Generally, you’ll be fine if you arrive at the airport 1 hour before a domestic flight and 2 hours before an international flight; if you show up late, tell an airline employee and he or she will probably whisk you to the front of the line. Bring a current, governmentissued photo ID such as a driver’s license or passport, and if you’ve got an E-ticket, print the official confirmation page; you’ll need to show your confirmation at the security checkpoint and show your ID at the ticket counter or the gate. (Children under 18 do not need photo IDs for domestic flights, but the adults checking in with them do.)

Security lines are getting shorter than they were during 2001 and 2002, but some doozies remain. If you have trouble standing for long periods of time, tell an airline employee; the airline will provide a wheelchair. Speed up security by not wearing metal objects such as big belt buckles or clanky earrings. If you’ve got metallic body parts, a note from your doctor can prevent a long chat with the security screeners. Keep in mind that only ticketed passengers are allowed past security, except for folks escorting passengers with disabilities or children.

Federalization has stabilized what you can carry on and what you can’t. The general rule is that sharp things are out, nail clippers are okay, and food and beverages must be passed through the X-ray machine—but security screeners can’t make you drink from your coffee cup. Bring food in your carry-on rather than checking it because explosive-detection machines used on checked luggage have been known to mistake food (especially chocolate, for some reason) for bombs.
Travelers in the U.S. are allowed one carry-on bag, plus a “personal item” such as a purse, briefcase, or laptop bag. Carry-on hoarders can stuff all sorts of things into a laptop bag; as long as it has a laptop in it, it’s still considered a personal item. The Transportation Security Administration (TSA) has issued a list of restricted items; check its website (www.tsa.gov/public/index.jsp) for details.

In 2003, the TSA will be phasing out gate check-in at all U.S. airports. Passengers with E-tickets and without checked bags can still beat the ticketcounter lines by using electronic kiosks or even online check-in. Ask your airline which alternatives are available; if you’re using a kiosk, bring the credit card you used to book the ticket. If you’re checking bags, you will still be able to use most airlines’ kiosks; again, call your airline for up-to-date information. Curbside check-in is also a good way to avoid lines, although a few airlines still ban curbside check-in entirely; call before you go. At press time, the TSA is also recommending that you not lock your checked luggage so screeners can search it by hand, if necessary. The agency says to use plastic “zip ties” instead, which can be bought at hardware stores and can be easily cut off.
