 This is CBS News on the Hour, sponsored by O'Reilly Auto Parts. I'm Christopher Cruz. The 4th of July holiday travel rushes upon us. At Dallas-Fort Worth International Airport, the lines seem impossibly long. Oh yeah, I get nervous. I don't like the crowds. I come early because people don't like to get up too early. That's how some are beating the crowds, but AAA's Aixa Diaz warns they won't drop anytime soon. With the holiday being on a Thursday this year, a lot of people are taking the whole week off.
