Ryanair has come under increasing pressure over its handling of flight cancelations which have disrupted the travel plans of 400,000 people.

Kerry McAuley and her family from Newtownabbey, Northern Ireland, had looked forward to a welcome break in London in February this year and had flights booked with Ryanair.
However, the day before the flight son Shea was taken seriously ill at school and rushed to hospital. Thankfully, he made a recovery but it meant the holiday, including a visit to Legoland in Windsor, did not go ahead.
"Ryanair gave me a flight credit and I booked flights to London for February 2018, which have now been cancelled," said Mrs McAuley.
"Ryanair have just given me another flight credit, again to be used to book flights within six months.
"This is no use to me whatsoever and I am disgusted by their attitude".
