For anyone thinking of traveling on Dec. 19, a change in plans may be in order. Airlines for America forecasts Friday, Dec. 19, as the busiest air travel day of the holiday season.
The lightest travel days are expected to be Christmas Eve, Christmas Day, New Year's Eve and New Year's Day.
"We expect 45 million customers will travel onboard U.S. airlines over the holiday period, and airlines are adding seats to the marketplace to accommodate the increase in demand. As more customers take to the skies this holiday season, travelers will continue to benefit from the significant investments U.S. airlines are making -- to the tune of more than $1 billion per month -- into amenities at the airport and in the skies that further enhance the travel experience," said John Heimlich, vice president and chief economist for Airlines for America.
