This holiday season is anticipated to break travel records, particularly at Atlanta's Jackson International Airport, the busiest in the U.S. AAA forecasts over 107 million people traveling by road, with an additional 7 million flying. The airport expects over 300,000 travelers on the busiest days, especially after Christmas and before New Year's. The travel window from December 20th to January 5th will see about 3.7 million travelers at this airport alone. More people are opting for road travel due to lower gas prices and high airline fares. Travelers are advised to prepare for long lines and arrive early: two hours for domestic flights and three for international ones.
