 It is shaping up to be one of the busiest travel days of the year. Elise Martinez reports from LAX. Traffic in and out of the airport has been very busy. We met a family of four from Tampa, Florida, heading back home. One of them had some travel tips. Definitely come early. Don't try to cut it an hour before your flight. Come like two hours before your flight. Check in right at that limit. Make sure your bag is underweight.
