Travelers across the United States reported long lines and delays at several major airports as a shutdown at the Department of Homeland Security (DHS) disrupted normal operations, according to airport officials and passenger accounts.
The disruption has affected security screening and immigration processing at some airports, leading to extended wait times for passengers during peak travel periods.
Authorities said the shutdown has limited staffing at certain DHS agencies responsible for transportation security and border control.
Airports and airlines advised travelers to arrive earlier than usual while officials work to manage the backlog. Some airports reported lines stretching through terminals as security officers processed passengers more slowly than normal.
Federal officials said contingency measures are being implemented to maintain critical security operations, but warned delays could continue until normal agency operations resume.
Travelers were urged to check flight updates and allow extra time before departures.
