The F-line runs from Castro down Market Street past San Francisco Civic Center and around Embarcadero to Fisherman's Wharf. You can hop off at San Francisco Ferry Building on a Tuesday or Saturday afternoon and enjoy Farmer's Market. If you're visiting San Francisco, be sure to include an F-line streetcar ride in your itinerary. It's perfect for getting between some of most common tourist attractions and you'll find ride worth every nickel of fare.

Now that you're packed, it's time to dress for airport. Avoid wearing a lot of jewelry or metal items. Try to wear a pair of tennis shoes or other comfortable shoes that doesn't have a metal support in sole construction (many thick-soled dress shoes and high-heeled women's shoes use these). If you pack your keys, cell phone or PDA in your pocket, prepare an empty pocket in your carry-on where you can easily place these items before you get to security checkpoint.

When you're at airport and about to go through security, most important thing you can do is to be prepared for next step in process. Before you enter security line, verify that there is not a shorter line at another gateway that you can use. As you enter line, have your boarding pass and driver's license or passport ready for inspection. Keep these items easily accessible as many airports require you to show them more than once.

As you approach security checkpoint, remove all metal items, keys, PDAs and cell phones from your person and place them in your specially prepared carry-on pocket. You may also want to remove your jacket and carry it over your arm until you get to check point.

At security checkpoint, take your laptop out of your carry-on. Place your laptop and jacket in provided containers. Place your carry-on bag on conveyor. As your items enter scanner, it's time for you to breeze on through checkpoint.

Be sure to follow instructions of security screeners. Remember they are there to ensure your security. If you are pulled aside for a random screening, be courteous to security personnel. They are there to do a job and being pleasant makes things a little nicer for both them and you.

A little commonsense and preparation can ease your way through airport security and get your flight off to a great start.
