Ryanair claims fewer than 2 per cent of its 3,000 flights have been affected by strikes in Europe.
They say there has been minor disruption in Belgium, where over 60 per cent of scheduled flights to and from Charleroi and Zaventem will operate today.
There were no flight disruptions in Ireland, Italy, Spain, Portugal, UK, France or Ireland, as the vast majority of Ryanair crews are working normally.
Strikes are taking place in Spain, Portugal and Belgium in a dispute over pay.
