Today is one of the busiest at South Florida airports as people head home from their New Year's vacations. Greg Chin at Miami International says 140-thousand people are expected to pass through today, so pack your patience if you are heading to MIA. Ft. Lauderdale-Hollywood International also has extra staffers on hand to get people through security lines as quickly as possible. Passengers should arrive at least 2 hours before departure time to play it safe.
