Could a DHS Shutdown Trigger Major Flight Delays at Las Vegas Airport?

Officials at Harry Reid International Airport (LAS) are monitoring the risk of significant operational disruptions amid the possibility of a U.S. Department of Homeland Security (DHS) shutdown. As one of the nation's busiest airports, handling a record 57.6 million passengers in 2023, LAS is particularly vulnerable to staffing shortages within the Transportation Security Administration (TSA), a key agency under DHS.

Disputes over federal policy could lead to a lapse in funding for DHS. This would directly impact the TSA, which is responsible for all airport security screening operations across the United States.

The Impact of Working Without Pay

During a government shutdown affecting the DHS, approximately 95% of TSA employees are designated as "essential" personnel. This means they are federally mandated to report to work but will not receive their paychecks on time. This situation creates significant financial hardship and has historically led to a sharp increase in unscheduled employee absences.

For example, during the 34-day government shutdown in 2018-2019, the TSA reported that its unscheduled absence rate surged to 10%, more than three times the normal rate, according to Government Executive. Such a spike in "call outs" at a major hub like LAS would inevitably lead to longer security lines, missed flights, and cascading delays throughout the national air system.

Lessons from Past Shutdowns

The consequences of prolonged shutdowns extend beyond immediate operational challenges. They create long-term damage to staffing and morale within critical aviation agencies. Testimony from the TSA revealed that a 43-day shutdown in 2025 resulted in a 25% higher attrition rate compared to the previous year, as reported by AJC.com. Experienced officers left for more stable employment, making it harder to maintain security standards.

While a shutdown limited to DHS would not halt pay for air traffic controllers, who are employed by the Federal Aviation Administration (FAA) under the Department of Transportation, past government-wide shutdowns have shown the broader risks. The Brookings Institution noted that these events force the FAA to suspend the hiring and training of new controllers, worsening chronic staff shortages that already strain the system.

For passengers traveling through Las Vegas, a DHS shutdown means preparing for potential uncertainty. Even if air traffic control remains fully operational, significant delays at TSA checkpoints can disrupt airline schedules and create a stressful travel experience.
