In this new era of heightened airport security, it is important to...

1. Check the Permitted and Prohibited Items list on the TSA website: http://www.tsa.gov/travelers/airtravel/prohibited/permitted-prohibited-items.shtm
2. As you head toward the security area, take a deep breath and remain calm. Check and be sure you have your boarding pass and a government-issued photo identification card ready for security personnel.
3. Place valuables (jewelry, laptop computers and cash) only in carry-on baggage.
4. Before you get to the screening checkpoint, place your mobile phones, keys, loose change, money clips, PDA's, lighters, and metal hair accessories in your carry-on bag.
   At the screening station, remove your laptop from its case and send it through the X-ray machine in its own plastic tray. Don't forget to label your laptop computer with your name, address and telephone number. These are one of the most frequently forgotten items at screening checkpoints.
5. Store all undeveloped film and cameras containing film in your carry-on baggage. Ask for a hand inspection if you want to ensure that the X-ray machine does not damage your film.
   If you are bringing a gift to friends or relatives, wrap it after you arrive at your destination. Otherwise, you might have to unwrap it to pass through security -- even if it is in checked luggage.
6. Avoid carrying bottles of liquid through the screening checkpoint.
7. Take your time unpacking and repacking your belongings -- or you may leave your laptop, keys, or wallet behind.
8. Be prepared to remove your shoes and belt because many contain small pieces of metal.
