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

MAS said in a statement Sunday that following the arrangement, its MH4 flight on Sunday, which was scheduled to depart KLIA for London at 10.45am, has been re-timed to depart at 5.35am Monday (Feb 6) and arrive in London at 11.05am the same day.

“The return flight MH1 of Sunday, scheduled to depart London Heathrow for KLIA at 10pm, has also been re-timed to depart at 1.50pm Monday, and arrive at KLIA at 10.10am Tuesday.

“Customers are advised to log on to www.malaysiaairlines.com and view the UK travel alerts' updates or call Malaysia Airlines' 24 hours toll-free number 1300 88 3000 (within Malaysia) or +603 7843 3000 (from outside Malaysia) for the latest information on this situation,” the statement added.

Meanwhile, AFP reports that the Heathrow Airport cancelled 30% of its flights Sunday 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 around 400 flights.

Most of Britain was on amber alert, the Met Office national weather service's second-highest severe weather warning.
