In 2025, 9.8 billion passengers traveled by plane, and over 106 million of them went through Hartsfield-Jackson Atlanta International Airport (ATL), according to the Airports Council International. However, despite being the world's busiest airport every year since 1998 (excluding 2020), Atlanta isn't the worst major airport in Georgia for cancellations. Instead, that title goes to Georgia's second biggest hub, Savannah-Hilton Head International Airport (SAV), based on the percentage of cancellations. While an airport as busy as Atlanta does experience a high number of cancellations, its position as a major hub actually protects it more than a smaller airport like Savannah-Hilton Head. 10 on the list of most flight cancellations in the U.S., with 2.07% cancelled, according to Insure My Trip.
