Security wait times at Hartsfield-Jackson Atlanta International Airport (ATL), the world’s busiest by passenger volume, continue to vary dramatically on March 22, 2026, as the partial U.S. government shutdown drags into its second month, leaving Transportation Security Administration (TSA) officers unpaid and contributing to staffing shortages, absenteeism and unpredictable lines.

Real-time data from the airport’s official tracker at atl.com/times and third-party aggregators like Takeoff Timer and OnAir Parking showed average standard security wait times around 14 minutes as of midday local time, with peaks earlier in the overnight hours reaching 45 minutes from midnight to 1 a.m. and lows of zero during the quietest overnight slots. TSA PreCheck lanes remained significantly faster, often under 5 minutes when open.

However, passenger reports on social media and Reddit megathreads painted a more volatile picture. Early Sunday morning updates from r/Atlanta users described waits climbing to 75 minutes or more at the main domestic checkpoint during peak arrival periods, with some travelers advising 3+ hours of buffer time before flights. Lines have fluctuated wildly throughout the weekend: long queues spilling into baggage claim areas on Saturday and Friday, then easing briefly midday before building again.

The inconsistency stems directly from the ongoing partial shutdown affecting the Department of Homeland Security (DHS), which funds TSA. With no appropriations bill passed, many TSA employees have missed paychecks — some their second full cycle — prompting high call-out rates (reported as high as 36% on certain days in mid-March) and resignations. Nationwide, absenteeism has hovered around 10-30% above normal, hitting busiest hubs like ATL hardest during spring travel season.

Airport officials and airlines, including Delta Air Lines (ATL’s dominant carrier), have repeatedly urged passengers to arrive at least three hours early for domestic flights and four hours for international ones. Standard guidance recommends two hours pre-departure, but current conditions demand extra cushion for parking, check-in, bag drop and the trek to gates via the Plane Train, which adds 10-20 minutes post-security.

The main domestic checkpoint — serving the bulk of passengers — has seen the most strain, with queues occasionally extending beyond the atrium into baggage claim. North and South checkpoints (including PreCheck-only lanes) and the international terminal have generally moved faster, sometimes clearing in under 10-15 minutes during off-peak. International departures, including Concourse F, reported shorter waits overall.

The crisis has compounded other factors: spring break crowds, potential weather disruptions earlier in the month and general post-pandemic travel recovery. Flight delays and cancellations have risen, though not always directly tied to security — with hundreds affected on peak days per FlightAware data. Passengers missing connections due to long lines have added frustration, with some reporting hours-long backups that force rebooking.

TSA and airport leaders stress that security remains the priority, with available staff prioritizing threat detection over speed. PreCheck, CLEAR and TSA PreCheck enrollment continue to offer the best relief, with dedicated lanes seeing minimal delays. Officials remind travelers that wait times fluctuate hourly — peaking typically 5-9 a.m. and late afternoons/evenings — and urge checking real-time tools before heading out.

The official ATL wait time page provides minute-by-minute updates across checkpoints, though some users note it lags or underreports during surges. Community-sourced trackers on Reddit and apps like MyTSA supplement with crowd photos and firsthand accounts. As the shutdown persists without resolution — despite recent political threats and offers like Elon Musk’s proposal to cover salaries — experts warn conditions could worsen if staffing erodes further.

Travelers are advised to:
– Enroll in TSA PreCheck or CLEAR if eligible for expedited screening.
– Monitor atl.com/times, the MyTSA app or airline alerts.
– Arrive early, especially for early-morning or peak flights.
– Consider ground transportation alternatives if driving to the airport amid potential parking backups.

As Congress remains deadlocked over DHS funding amid immigration policy disputes, Atlanta’s airport — handling over 100 million passengers annually — exemplifies the broader national impact on air travel. With no immediate end in sight, the message from officials is clear: plan for delays, pack patience and prioritize buffer time to avoid missing flights.
