Updates total cancellations, delays.
The US Federal Aviation Administration (FAA) will stage planned flight cancellations over seven days before reaching a full 10pc reduction at key airports.
A 4pc reduction in operations will take effect today at 40 high-traffic airports across the US before ramping up to 6pc by 11 November, 8pc by 13 November and 10pc by 14 November, according to the US Department of Transportation.
Airlines will be allowed to use their own discretion to decide which flights are canceled to satisfy the order, which does not require a reduction in international flights.
Total cancellations within, into or out of the US today reached 850 by 12pm ET today, according to flight-tracking site FlightAware, marking the highest rate month-to-date. Delays totaled 1,686. More than 660 cancellations are expected tomorrow, and at least 265 are planned for Sunday.
US flight cancellations have totaled 1,875 since 1 November, and delays totaled 32,865. The count also includes mechanical, weather-related, and other incidents.
US transportation secretary Sean Duffy had warned the US earlier this week that an extended US government shutdown would cause mass flight cancellations and airspace closures, blaming Democrats for not voting to reopen the government.
Air traffic controllers and Transportation Security Administration (TSA) agents have been working without pay and with fewer staff since the partial US government shutdown started on 1 October. Staffing shortages prompted the FAA to periodically issue temporary ground stops at some airports because of a lack of air traffic controllers, while TSA staff shortages led to hours-long security check-ins.
The planned flight reductions may add downward pressure to US jet fuel prices because of lower demand. The Argus US jet fuel index already fell by 22.6¢/USG week-on-week to $2.41/USG by the end of trade 6 November.
