In Atlanta, the world’s busiest airport had its busiest day ever. Hartsfield-Jackson Atlanta International Airport broke a traffic record on Thursday when 111,000 passengers, airlines crew and airport employees were screened at security checkpoints. The second busiest day followed on Friday when 109,960 people were screened, according to the TSA.

With 104.6 million passengers, the Atlanta airport was the busiest in the world last year, according to Airports Council International.
