Heathrow to operate reduced schedule on Tuesday
Heathrow Airport is operating a reduced flight schedule today, Tuesday December 21.
The airport reopened for partial service on Monday after being shut down on Sunday.
Just one of its two runways was open, however, and only a third of scheduled flights operated. Long-haul flights were given priority.
Further snow is forecast across Europe on Tuesday and the airport has warned of the likelihood of further delays and cancellations.
Airlines are already struggling to clear the backlog of stranded passengers due to most flights around Christmas being fully booked.
Criticism of the airport's ability to handle extreme weather continues in the UK.
The mayor of London, Boris Johnson, has weighed into the argument, saying: "It can't be beyond the wit of man, surely, to find the shovels, the diggers, the snowploughs or whatever it takes to clear the snow out from under the planes, to get the planes moving and to have more than one runway going."
A statement on Heathrow's web site reads: "We are truly sorry for the disruption the weather is causing to our passengers.
"We are doing everything we can to get you on your journey."
Passengers taking flights into and out of Heathrow are urged to check with their airline before leaving home.
