As of 7:45 a.m., there were more than 30 cancellations into and out of Minneapolis-St. Paul International Airport.

St. Paul International is one of 40 airports to be affected this weekend as the FAA reduces national air traffic amid the government shutdown. An estimated 41 flights at MSP may be cut just on Friday.

Overall, United has canceled more than 100 flights each day, from Friday, Nov. 7 through Sunday, Nov. 9, the airline's website showed. Of those, 34 United flights scheduled to depart or arrive at Chicago O'Hare International Airport Friday were cut, with that number increasing to 38 Saturday.

FAA orders flight reductions at major airports, including MSP. 4% cut now, possibly 10% by Nov. 14, due to federal shutdown, affecting travelers.

Staffing-related cancellations are only growing worse under the FAA directive, the data show. On Sunday, of the 1,704 cancellations across the nation, 819 were FAA-mandated reductions and another 885 were tied to delays from staffing problems.

DULUTH — As major airline hubs across the nation work to trim their flight schedules per a federal directive, the ripple effects could easily impact smaller operations such as the Duluth International Airport.
