Transcript for Must-know airfare hacks to find top summer vacation deals
think about summer vacation and that means getting the best bank for flights and Becky Worley has the details. Reporter: If you're like a working mom of a 7 week old, getting your summer travel planned is a major feat. We'll fly to the west coast to visit both sets of grandparents. Reporter: Vanessa, her husband and three kids are traveling from San Francisco to New York to visit family, then a quick stop in Boston before heading home to California.
