Northern and eastern Scotland, northeast England and Northern Ireland have a yellow warning for snow and ice until Friday. The warning also covers a broad swathe of southern England, including all the London airports plus those in Birmingham and Cardiff.

The Met Office warned to expect roads and railways affected by ice and snow, “leading to difficult travel conditions” in places.

Yellow is the less serious of the Met Office’s three warning categories behind amber and red. The category is used when severe weather is “possible” and could affect the public.

“Yellow means that you should plan ahead thinking about possible travel delays, or the disruption of your day-to-day activities,” the Met Office said.

Loganair said: "Given the yellow warning for snow forecast on Thursday 9 March until Friday 10 March 2023 across the UK, and the potential for travel disruption, we are offering customers the opportunity to adjust travel plans without charge.

"You can choose to rebook on an alternative flight up to seven days from your original travel date. There will be no change fee or difference in fare payable. If a seat is available on an alternative flight, you can transfer your booking to that flight without charge on a first-come, first-served basis.

"We plan to fly all our scheduled services. We have standby aircraft and crews in place to help recover any disrupted services as soon as possible once weather conditions permit. Please note that unless your flight is cancelled, no refund will be offered for any operating service."

The CAA tweeted: "Yellow weather warnings are in place in parts of England, Scotland, Wales, and Northern Ireland between now and Friday. If you’re affected by a flight delay or cancellation, make sure you understand what you are entitled to."
