US airports report over 20 air traffic controller shortage incidents in one day

Transportation secretary says figure is one of the highest we've seen' since 1 October as shutdown drags on

US airports have reported more than 20 incidents of air traffic controller shortages on Saturday, said Sean Duffy, transportation secretary, in the latest sign of the government shutdown's impact.

A ground stop was issued by the agency at Los Angeles international airport due to the air traffic controller staffing shortages at around 11.30am ET (15.30 GMT). The restriction covered most of the southern California region and delays are likely when flights resume.
