Flights to and from Heathrow Airport will be disrupted for a second day following snowfall on Sunday (December 10).
The airport has warned passengers to check with their airline before travelling on Monday (December 11).
A spokesman said on Twitter: "Some flights at Heathrow will be disrupted today due to crew and aircraft being out of position following yesterday’s weather.
"As always, our advice to passengers is to check your flight status with your airline before coming to the airport.
"If your flight is cancelled, we ask that you do not travel to the airport and keep updated via your airline’s website. We're working with our airline partners to return aircraft to where they need to be and full service recovery remains the focus.
"The safety and comfort of our passengers is always our first priority and we're working closely with our airlines to ensure affected passengers are looked after.
"We apologise to those whose travel has been impacted and regret the inconveniences that has been caused."
A yellow weather warning for ice is in place across the south east until 11am on Monday, said the Met Office.
The chief forecaster said: "With cold conditions and some snow lying over parts of England, as well as further rain pushing in from the south east during the second half of the night, icy stretches are expected to form on untreated surfaces.
"At the same time some snow may fall over parts of Kent, Sussex, Surrey and Hampshire. This is only a low impact warning with impacts much less widespread and less significant than across parts of England and Wales on Sunday."
