Airlines Cancel 1,500 US Flights Monday

Airlines on Monday canceled more than 1,000 U.S. flights for a fourth consecutive day as government flight cuts and air traffic staffing absences continue to wreak havoc with aviation.

FlightAware, a flight tracking website, said by 7:45 a.m. ET, more than 1,550 flights had been canceled and 1,200 delayed Monday after 2,950 flights were canceled and nearly 10,800 delayed Sunday in the single worst day for flight disruptions since the government shutdown began on Oct. 1.
