British Airways has halted two dozen domestic and European flights due to Storm Pia.
Scottish airline Loganair has also grounded some services, while railway service TransPennine Express has issued “do not travel advice”.
BA, which is owned by International Consolidated Airlines Group SA (LSE:IAG), said air traffic control restrictions were imposed because of the storm, leading to necessary adjustments in their schedule.
In a statement to Sky News, BA apologised for the disruption, assuring customers that they are diligently working to restore flight operations.
Passengers affected by flight cancellations are protected under UK law if the flight departs from a UK airport, arrives at a UK airport on a UK or EU airline, or arrives at an EU airport on a UK airline.
In the event of a cancellation, the airline is obligated to provide either a refund or an alternative flight, whether with them or a competitor.
Travellers have the discretion to choose between proceeding with the journey at that time or rescheduling for a later date.
While some airlines are offering only refunds, passengers are entitled to opt for a new flight if they prefer.
