Why are TSA security lines so long?
The drivers of rising airport security wait times
Several overlapping factors have pushed wait times at U.S. security checkpoints much higher. A partial federal shutdown affecting the Department of Homeland Security has disrupted routine operations at some airports, reducing staffing flexibility and complicating checkpoint scheduling. At the same time, higher passenger volumes tied to peak travel periods have strained the remaining resources, producing unusually long queues at major hubs.
This situation has been particularly visible at airports expecting surges in travellers — for example, those serving spring-break routes — where check-in and screening demand can spike abruptly. When staffing levels are tight, even modest passenger surges multiply into long waits because checkpoints cannot open extra lanes or process arrivals faster.
Key elements adding to the problem
- Reduced operational staffing tied to the department-level funding disruption.
- Elevated passenger numbers at certain airports during peak travel periods.
- Limited short-term flexibility to redeploy screeners or open additional lanes.
How travelers can reduce risk of missing flights
- Arrive much earlier than usual: allow additional time beyond routine recommendations.
- Use expedited programs: TSA PreCheck or Global Entry lanes, where available, are typically much quicker.
- Travel light through security: be prepared to remove electronics and liquids to help speed processing.
- Monitor airport advisories and expect occasional last-minute changes to operations.
Airport authorities and federal officials are taking steps to manage the immediate pressure, but the length and severity of delays will depend on how quickly staffing and funding questions are resolved and whether passenger demand normalises.
