ATLANTA (AP) — Officials are projecting a record-breaking day in traveling at the world's busiest airport in Atlanta.

Hartsfield-Jackson International Airport spokesman Reese McCraine tells multiple news outlets that officials expect at least 88,000 people will have passed through the airport by the end of Sunday. McCraine says the prior record for the year was 80,000 people on Columbus Day.

The busy travel day comes during a global travel alert with warnings of increased terror threats.

WSB-TV says extra security and officers were in place to deal with the high volume of travelers at the airport. Police vehicles lined up outside the airport.

The Transportation Security Administration brought in every available agent to keep the lines at the checkpoints moving. The TSA recommends getting to the airport at least two hours beforehand.
