The Globe and Mail reports in its Saturday, Nov. 8, edition that hundreds of flight cancellations occurred across the U.S. on Friday as airlines began following the FAA's order to reduce service due to the government shutdown. An Associated Press dispatch to The Globe reports that while some passengers struggled to adjust, many found their flights still operating as reductions were phased in at major airports. The FAA identified 40 airports for the slowdown, including hubs like Atlanta, Dallas and Los Angeles. More than 800 flights were cancelled nationwide, four times the number from Thursday, according to FlightAware. Not all were due to the FAA order. Airports in Chicago, Atlanta, Denver, Dallas and Phoenix led the way with the most disruptions, FlightAware said. United and American Airlines announced Friday that they quickly rebooked most travellers, with over half of United's passengers reaching their destinations within four hours of their original plans. Many routes cut on Friday were shuttle flights in the Northeast, Florida, and between Dallas and smaller cities, according to Cirium. The FAA noted that reductions will start at 4 per cent of flights at busy airports, increasing to 10 per cent a week later.
