More than 2,100 flights have been canceled on Monday as the government shutdown continues to place strain on aviation officials.

Flight delays and cancellations have impacted travelers after the Federal Aviation Administration ordered a reduction in flights, citing staffing and safety concerns. Advertisement

As air traffic controllers near their sixth week of working without pay, staff shortages have become more common.

On Sunday, nearly 3,000 flights flying into, out of, or within the U.S. were canceled. An additional 11,200 flights were delayed.
