WATCH: Why you should book summer travel now

Clint Henderson, managing editor of "The Points Guy," offers advice on booking summer travel and navigating airport security efficiently. The guidance comes as millions of Americans prepare for peak summer travel season, when flights fill quickly and TSA wait times typically lengthen. Henderson's tips are intended to help travelers secure better fares and reduce stress at security checkpoints during the busiest travel period of the year. Early booking—particularly for summer flights—typically yields lower prices as airline capacity tightens closer to departure dates.
