A number of flights to and from Dublin have been affected by the latest round of Ryanair cancellations.

Six flights to and from the capital are among several affected on Tuesday - including services to Berlin, Glasgow and Krakow.

The Irish carrier has published the full list of flight cancellations for the next five weeks.

It says the cancellations have been allocated, where possible, to Ryanair’s bigger base airports and routes with multiple daily frequencies.

Customers affected will be e-mailed with offers of alternative flights or full refunds.

Ryanair says the cancellations are due to several factors, including a backlog of holiday leave to pilots and cabin crew.

The company is moving its holiday year from the current system of April to March to a calendar year of January to December from January 2018.

It says the backlog of crew leave must be allocated before December 31st.

Ryanair says it "sincerely regrets and apologises for these cancellations".

Ryanair's chief executive Michael O’Leary says: "This is a mess of our own making. I apologise sincerely to all our customers for any worry or concern this has caused them over the past weekend.

"We have only taken this decision to cancel this small proportion of our 2,500 daily flights so that we can provide extra standby cover and protect the punctuality of the 98% of flights that will be unaffected by these cancellations."

The Commission for Aviation Regulation says it wants all passengers affected to be aware of their rights.

"Passengers who remain unclear about their entitlements as set out in EC Regulation 261/ 2004, or who have further queries in relation to same, should contact this office at info@aviationreg.ie or on 1890-787-787 or + 353-1-6611700", it says.
