Starting Friday, airlines will cancel flights at busy airports across the country, including the Minneapolis-St. Paul International Airport. The Federal Aviation Administration directed airlines to cut traffic by 10 percent to keep travelers safe during the government shutdown.

Air traffic controllers have been working without pay since October 1 and that has exacerbated staffing problems. The shutdown is now the longest in United States history.
