Nov. 17, 2007 — -- So you and millions of other Americans are about to brave the masses and head out into the Thanksgiving holiday travel season.

Airplane cabins are expected to be more packed than ever as travelers cope with crowded skies, unpredictable weather and higher prices.

While you can't control the weather or the airlines, there are simple things you can do to help smooth the way. ABC News consulted travel experts to compile tips for making every aspect of your trip easier.

We all know about long lines for checking baggage and security. But during the holidays, parking at many airports can pose an even bigger challenge.

Airport parking lots tend to fill up during the holidays, forcing travelers to find alternative parking and possibly causing them to miss their flights.

"If you miss your flight for any reason, it's very unlikely during peak winter travel season that you'll be accommodated on another flight in a reasonable period of time," said Chris McGinnis, editor of Expedia Travel Trendwatch. "So you cannot miss your flight. It's very important to give yourself a huge time cushion."

Do some research by calling the airport or checking its Web site. Consider making a reservation at an off-site lot, and look into public transportation options.

As for those nasty check-in and security lines, always check with your airline, the Transportation Security Administration and the airport before leaving home.

Other Web sites offer new tools to help travelers this year. Orbitz just launched a new service for fellow travelers to post firsthand reports of their experiences at various airports with security, check-in and other hassles of travel.

Be sure to pick a seat now or check in early from home. Travelocity's editor at large Amy Ziff suggests carrying snacks and some beverages purchased after you've gone through security before boarding your plane.

And bring extra medication with you in your carry-on because you never know how long you might be stranded somewhere or when you will see your bags next.

If you haven't booked a ticket already, you are probably too late to get a seat, let alone a good fare.
