The low-cost carrier said “the knock-on effect” of the bad weather and ongoing European air traffic control staff strikes may cause further disruptions throughout the day, including delays and cancellations.
Affected customers are being notified by email and text message and advised of their options of a refund or free switch to the next available flight, Ryanair explained.
“Ryanair sincerely apologise for these weather and ATC disruptions which are entirely beyond our control,” the carrier added.
Posting on Twitter, Stansted said it advises passengers travelling today to check the status of their flight with Ryanair before setting off for the airport.
