Authorities quickly initiated security protocols, leading to the suspension of light rail services connecting the airport to surrounding areas. This decision was made to ensure passenger safety while the investigation was underway. The investigation caused significant delays for both arriving and departing flights, leaving travelers stranded in long lines at check-in counters and security checkpoints.

In addition to the light rail suspension, several key roadways surrounding the airport were temporarily closed as part of the security measures. These closures further exacerbated the situation, with traffic congestion spreading throughout the surrounding areas. Commuters attempting to navigate the roadblocks faced long delays as they tried to access the airport or other destinations. The Baltimore-Washington Parkway, a major highway leading to the airport, experienced heavy congestion, and motorists were advised to seek alternate routes. The disruptions not only affected those flying in and out of BWI, but also travelers using the roadways to reach nearby businesses and residential areas.

As the bomb threat investigation progressed, airport authorities and local law enforcement worked swiftly to clear the area and resume normal operations. Passengers were advised to check flight statuses, as many experienced delays or cancellations due to the heightened security measures. While the all-clear signal was given later in the afternoon, the effects of the disruptions continued to ripple throughout the day. Airport officials assured the public that safety was their top priority and emphasized that they were working with local authorities to fully investigate the threat. By the evening, services began to return to normal, though travelers were still urged to anticipate possible delays as a result of the afternoon’s events.
