 The last day of the July 4th weekend saw an astounding 3 million passengers passing through the nation's airports. Even though the TSA put extra agents on duty, the news had plenty of their always popular long lines at airport stories. And I have a feeling some folks missed flights because they got to the airport late and or security lines were unusually long. My advice, cut in line. But is that proper protocol? From America's number one travel radio show, this is your Arm World Travel Minute. I'm Rudy Maxa. There is, of course, such a thing as proper protocol and rules at airports. But I recommend this.
