 When it's all said and done, this 4th of July travel period is expected to break records. And ABC's Morgan Norwood says the travel rush culminates this weekend. American Airlines is looking at tomorrow as the busiest day of the summer for them. With more than 6,500 flights taking off, going to be busy for Delta and United as well. But far more travelers, more than 60 million, will be taking that road trip over this holiday stretch. Up 2.8 million more than last year.
