Airports will be on extra high security this holiday weekend. If you're flying, this sounds like a good tip from FAA Administrator Marion Blakey:

One of the first things I go to is my PDA, or telephone, because now we have a brand new service, www.faa.gov/wireless , and you can go on and actually pick up what the story is at your airport before you go," she said on NBC. "Are you running into any ground delays? Is there weather to be aware of? In fact, you can go to your specific airline and see what's the story on the flight. It lets you schedule, you're more in control and it really does give you a way of understanding the situation rather than just getting there and saying, 'What's going on.'"...The same information is available on the regular FAA Internet site for people not using a wireless device such as a personal digital assistant or cell phone.
