DUE to the heavy overnight snowfall in the United Kingdom, London's Heathrow airport has worked out a revised flight schedule for yesterday with all airlines, to minimise disruption caused to passengers by the poor weather.

MAS said in a statement yesterday that following the arrangement, its MH4 flight, which was scheduled to depart KLIA for London at 10.45 am yesterday, has been re-timed to depart at 5.35 am today and arrive in London at 11.05 am the same day.

The return flight MH1 yesterday, scheduled to depart London Heathrow for KLIA at 10 pm, has also been re-timed to depart at 1.50 pm today, and arrive at KLIA at 10.10 am tomorrow.

"Customers are advised to log on to www.malaysiaairlines.com and view the UK travel alerts' updates on this situation," the statement added.

Meanwhile, a global news agency reports that the Heathrow Airport cancelled 30 per cent of its flights yesterday to cope with heavy snowfall overnight and possible freezing fog at Europe's busiest passenger air hub.

Heathrow said up to 10cm (four inches) of snow were expected to fall which, without reductions to the flight schedule, would cause major disruption at the west London airport.

"We deeply regret any disruption caused to passengers by the cold weather," said Heathrow's chief operating officer Normand Boivin.

"Reducing the flight schedule means we can fly as many people as possible and return the airport to normal as quickly as possible."

The changes could affect approximately 400 flights.
