More than 3 million travelers screened at US airports in a single day. That's a record

Travelers heading home after the Thanksgiving holiday are setting a record. The Transportation Security Administration says that it screened nearly 3.1 million travelers on Sunday, breaking the previous record by about 74,000. That mark was set on July 7, also a Sunday after a holiday, July Fourth. Hundreds of thousands of travelers were delayed or had their flights canceled. FlightAware says more 6,800 flights were delayed on Sunday, with the highest numbers at Hartsfield–Jackson Atlanta International Airport and Chicago’s O’Hare Airport.
