  • US DOT orders flight cancellations up to 10% at 40 High Impact Airports
  • Cancellations will gradually increase from 4% to 10% over 7 days
  • Total number of cancellations each day could reach more than 4,000

Update 16 November — FAA rescinds all restrictions effective 17 November 06:00 ET

Citing a continued decrease in staffing triggers across the National Airspace System, the FAA is rescinding its order mandating cancellations at 40 major airports around the US. Also lifted are restrictions on business and private aviation at certain airports. 

Update 14 November — FAA decreases cancellations to 3% after “rapid decline” in staffing triggers

Citing a “rapid decline” in staffing triggers at air traffic control facilities, the FAA says it will decrease the required number of cancellations at 40 major airports to 3%, effective 15 November. 

Update 12 November — FAA holds cancellations at 6% after improvement in staffing levels

The FAA announced late Wednesday, 12 November that due to improved air traffic control staffing levels, airlines will not need to cut additional flight capacity at the 40 “high impact” airports. The mandated cancellation rate will hold at 6%. Flights by Part 91 and non-scheduled Part 135 operators at ATL, BOS, DCA, DEN, DFW, EWER, IAH, JFK, LAX, ORD, PHX, and SEA remain on hold.

Read the full revised order below.  

Amid the ongoing federal government shut down, now the longest in history, the US is ordering airlines to slash their schedules by up to 10% at 40 “high impact” airports around the country. US Transportation secretary Sean Duffy says the cuts are necessary to retain the required levels of safety through ongoing strain on the National Airspace System (NAS). Air traffic controllers and other FAA employees supporting the NAS have been working without pay since the shutdown began at the beginning of October. 

The plan to reduce the number of allowed flights in major markets was first floated on Wednesday, 5 November and officially released on Thursday evening. Cuts go into effect on Friday.

You can follow which airports are most impacted by delays and cancellations on the Flightradar24 disruption map. Review live disruptions as well as problems for the day ahead.

How do the cuts work?

Airlines are being instructed to cut a graduated percentage of flights beginning 7 November. Cuts are based on the “total daily scheduled domestic operations between 6:00 a.m. and 10:00 p.m. local at each airport.” Airlines must cut 4% of their flight program by 06:00 EST on 7 November. The reduction required increases to 6% on 11 November, 8% on 13 November, and 10% on 14 November and each day thereafter.

How are the airlines impacted?

The US’ ‘big four’ airlines—American, Delta, Southwest, and United—are cancelling the most flights, given their relative size, but smaller airlines operating in some markets are also greatly impacted. The FAA’s emergency order directs each 14 CFR part 121 and commuter or scheduled 135 air carrier operating at these 40 airports to implement reductions to their schedules.

As of the evening of 6 November, cuts for Friday, 7 November are being put in place.
