Getting Through Airport Security More Quickly

Laptop bags that may not require you to remove your computer. Luggage concierge services that enable you to check your bags before you arrive at the airport. PDAs to display your mobile boarding pass.

These gadgets and services can help you speed through security, and they won't hit your wallet too hard.

Here are some tips to guide you through deciding whether the extra costs are worth it.

Laptop sleeves: Consider bringing your laptop in a sleeve.

Skooba Design sells a laptop sleeve that you can carry on your own with removable shoulder strap and can unfold to lie flat on the airport X-ray machine belt.

The Transportation Security Administration will allow you to keep your laptop in such bags during the screening process if security can capture a clear and unobstructed image of the laptop.

Skooba's Netbook Neo-Sleeve is billed as a form-fitting, stretchy and cushy case that protects your laptop without adding bulk. There's a front pocket for a power adapter, though you will want to keep the computer alone in the sleeve during screening. A range of so-called "checkpoint friendly" laptop bags can be found on eBags.com.

TSA does not approve specific bags or offer a guarantee you won't have to remove your computer, but it has encouraged manufacturers to design bags that will allow screeners to obtain a clear image and give travelers the best shot at being able to keep computers in their bags.

Bottom line: It's worth the cost if you regularly carry a laptop.

Hotel bag checks: Consider checking your bags at your hotel.

For instance, Disney offers a free luggage concierge service at some of its Walt Disney World Resort hotels in Orlando, FL. If you're departing domestically on a designated airline, you can get your boarding pass and check your luggage at the hotel, bypassing airport check-in completely.

Disney says guests have to visit the hotel airline check-in desk up to three hours before their flight. Delta, United and AirTran are among the participating airlines.

Also some parking lots near major airports, including the Atlanta airport, allow you to check your bags for free. Only certain airlines participate but it can free you up from carrying your bags to the terminal.

Bottom line: If it's free, what's the harm.

A faster boarding pass: Consider not printing your boarding pass at all.

Travelers with Web-enabled mobile devices like a BlackBerry or iPhone can download their boarding passes, then have hand over the devices for scanning by federal security screeners and airline gate agents. The service is not yet widely available but it's expanding. Continental offers the mobile boarding pass option at more than two dozen airports.

A smartphone can cost $199 or more, but hey, you also get to call your friends, check your Facebook page and text your arrival time to the person picking you up. Some airlines even offer you, for a fee, the ability to surf the Web with the devices while on your flight.

If you have to print out your boarding pass at the airport, save time by doing it at a self-service kiosk.

Bottom line: Don't buy a smartphone just to speed through security, but it is a nice device to have if you travel a lot.

Be prepared: Make sure to have your boarding pass and identification at the ready. Not having to fumble around will save you a few minutes.
