The action is intended to make up for the airport's passenger cap, which will limit the number of flights it can operate into and out of Dublin during the holiday season.

According to the airline, during the busy Christmas season, it would have typically had an extra 270,000 seats to and from Dublin.

However, Dublin Airport's annual passenger ceiling of 32 million has been achieved, forcing the aviation authority to set restrictions on the quantity of optional flights throughout the winter, including Christmas.

Due to the issue, Ryanair has frequently warned that its tickets into and out of Dublin might increase dramatically over the Christmas season.

As a result, it is advising anyone who want to travel to book early.

"Currently today in late August, our lowest fares from London to Dublin on Friday 20, Saturday 21 or Sunday 22 December are rapidly approaching €100 one-way due to this Government's failure to allow airlines to run extra flights to/from Dublin this Christmas," Ryanair CEO, Michael O’Leary, said this weekend.

Nonetheless, some have questioned why the airline believes it has no choice but to raise its costs owing to the lack of seats, including James Lawless, the Minister of State at the Department of Transportation.

Mr O'Leary has repeatedly urged the government to act to raise the cap.

It was implemented in 2007 as a requirement for Terminal 2's planning authorisation because of worries about the road system's capacity to handle the increased traffic that would result from the airport accommodating more than 32 million people annually.

Ryanair contends that since the requirement was implemented, a significant increase in the number of passengers has used public transit to go to and from the airport, negating the need for road congestion.
