Flights from Spanish airports to the US delayed after glitch

Several flights from Madrid airport to the United States were delayed on Wednesday morning, information released on the website of Aena, which operates the airport, showed.

Flights by a range of operators were showing as delayed by up to several hours to Dallas-Fort Worth, Miami, and New York, according to the website. Reuters was not able to immediately confirm the reason for the delays.

The U.S. Federal Aviation Administration said on Wednesday it was working to restore a system that alerts pilots to hazards and changes to airport facilities and procedures that had stopped processing updated information. The glitch led to hundreds of flight delays in the US.
