Worried about the wait for security screening? Did you know you can find estimated wait times on the TSA's website, www.tsa.gov, which includes information for most US airports. The site doesn't offer actual wait times, but it does show the average and maximum wait times for the past month.
Many airports offer the same service. Theirs are usually current or fairly current wait times. Check out your airport's website for information. It just may save you some time or grief.
