United Airlines jets grounded by computer router glitch

Thousands of United Airlines passengers have suffered delays because of the latest fault

A computer fault has forced United Airlines to ground its flights in the US for the second time in recent weeks.

The firm blamed a "network connectivity issue" for the latest fault.

The two-hour long issue caused delays to more than 90 of its aircrafts, according to the FlightAware website.

The airline had to enforce a shorter flight ban on 2 June after incorrect data appeared in its flight planning system.

Shares in the firm fell more than 1.5% in morning's trade.

The cybersecurity blogger Brian Krebs tweeted that the issue had been caused by a computer router malfunction rather than a cyber attack or sabotage, a fact that was later confirmed by United itself.

Several Twitter users posted photos of blank United Airlines airport screens

United is not the only carrier to have suffered such an IT-related setback over the past few months.

In April, American Airlines had to ground dozens of its jets after a flight plan tablet app, used by its pilots and co-pilots, stopped working.
