Third of flights could face delays

A third of UK flights could be delayed by more than half an hour unless airspace is modernised, the Transport Secretary has warned.

The skies are “increasingly congested” and punctuality could be 70 times worse by 2030, Mr Grayling said. He told the Aviation Club in London this would be damaging for passengers and residents as aircraft are “held needlessly in stacks above urban areas”.

The Department for Transport believes new technology can improve the way the UK’S crowded skies are managed.
