Furious passengers took over Twitter to express their anger towards Heathrow Airport and especially British Airways on Monday (December 11).

According to passengers on social media, many of them were asked by the airline to queue for hours, while others claim they got on a plane but were asked to get off six hours later.

Other passengers expressed concerns over their luggage and feared not being able to find it at baggage reclaim (see video above).

In a statement, British Airways said: "We are very sorry that customers continue to suffer from the disruption to flights at Heathrow caused by the severe weather conditions that have affected airports across northern Europe.

"Time spent on de-icing aircraft to ensure safe operation plus air traffic control restrictions and the re-positioning of aircraft and crews from yesterday [Sunday] have led to further cancellations and delays today [Monday].

"We understand how frustrating this experience is for customers and we are offering refunds for those who no longer wish to travel from Heathrow today or tomorrow regardless of whether their flight is cancelled or not.

"We are also offering the opportunity for anyone not wishing to travel today or tomorrow to rebook their flight up until December 18.

"Customers who have had their flight cancelled can rebook to travel up to 14 days after the date of their original booking, subject to availability.

"We will also rebook customers with other carriers and to alternative destinations so that they can travel as soon as possible.

"We have additional staff at our call centres and at Heathrow to help customers and will continue to include all the very latest information for customers on ba.com."
