Dublin is a major airport and the current charges are well below other major european airports. But there is no point is in talking about what Ryanair pays the DAA.
DAA management caught out again and again with bad weather.
Just like LGW, LHR, EDI etc. Dublin remained open while there were closed with the same snow fall.
Next people will be saying that the airport should of being kept open when the light aircraft blocked the runway.
