Long security wait times at Hartsfield-Jackson Atlanta International Airport have caused major delays for travelers. The Department of Homeland Security shutdown is affecting workers, with 34% of the TSA agents in Atlanta reportedly calling out sick due to not receiving a paycheck. This has led to increased security waiting times, with the app to monitor wait times now working. Nearly 400 agents nationwide have already resigned due to the shutdown. New construction projects could cause further delays before reaching a TSA line. The airport has recommended that passengers arrive three hours before their flights, more if they have to check bags.
