German airline Lufthansa has cancelled dozens of flights on Monday due to strike action.
Around 100 flights departures and arrivals have been cancelled at airports in London, Manchester, Birmingham, Newcastle, Glasgow, Aberdeen, Edinburgh and Dublin. The German airports affected by the strike are Frankfurt, Munich, Dusseldorf and Hamburg.
The one-day strike is due to a pay dispute.
Passengers affected by the cancellations can re-book for free, Lufthansa said.
