Passengers at Heathrow Airport face a second day of snow chaos as wintry weather leaves flights cancelled and delayed.
Airline passengers face yet another day of queues and cancellations at airports across the capital with Heathrow worst hit.
Heathrow, London City Airport and Luton have advised passengers to check their flights before travelling.
British Airways customers have been urged to contact their flight operator directly after it made an agreement with Heathrow to amend services due to poor weather conditions.
A spokesman for Heathrow said some disruption was due to staff and planes being “displaced” due to Sunday’s freezing conditions.
A statement posted on the airport’s website said: “We’re working with our airline partners to return aircraft to where they need to be, and full service recovery remains the focus.
A spokesman for British Airways added: “Heathrow is continuing to experience severe adverse weather conditions. As a result of the forecast of continued bad weather we have agreed with Heathrow Airport, National Air Traffic Services (NATS) and other airlines to reduce our flight schedule from Heathrow on Monday December 11.”
Customers whose flights have been delayed have been warned not to travel to the airport.
