Ryanair boss warns of £400 flights to city loved by Brits and stag dos

Ryanair might be known for its incredible value when it comes to heading to pretty much every corner of Europe. But things are going to get a whole lot more expensive, according to the company's boss.

Flights of more than £400 each way have been mooted as the budget Irish airline tries to combat airport restriction issues.

It says without sorting this, prices could skyrocket to more than £800 for a return ticket to one of the most loved destinations in Europe that is incredibly popular with Brits and stag dos.

Millions of people fly with Ryanair every single year, making it the busiest airline in all of Europe.

As the summer months arrive, plenty of people will be heading off to some of the continents most loved destinations - just make sure you don't take any of these 24 items on its planes which includes one common item many might have in their hand luggage without knowing.

Some of the bargains up for grabs have been £15 flights to a theme park 'better than Disneyland Paris', with the same priced flights available to a top European city with the world's 'cheapest beer'. Plenty for everyone, then.

But for those heading to one particular destination, flights later this year could get extortionate.

And the situation has gotten that dire that Ryanair's CEO, Michael O’Leary, has called on the country's government to intervene and solve the issue.

We're talking about the city in which the airline is based: Dublin.

Dublin Airport operator DAA currently operates a 32 million passenger cap that was brought in as part of the building regulations when the airport’s second terminal was given planning approval by the local council.

But O'Leary said the cap was 'insane and stupid', claiming the limit on passengers will cost Ireland money and thousands of tourism jobs.

He told Newstalk’s The Pat Kenny Show: "If we had a Minister for Transport who was modestly interested in aviation or even modestly interested in economic growth and development - which his own aviation policy is at the heart of - he would fix this."

O'Leary says the removal of the cap could see upwards of 40 million people come to Dublin within four years, adding: "We’re opening new hotels, we’re developing new restaurants, the Wild Atlantic Way and all of these tourism facilities need continuing growth in visitor numbers."

But O'Leary warned that the cost of Ryanair tickets will be as high as €1,000 (£840) return for the 2024 Christmas period if the situation isn't resolved and more flights can't be organised, as part of business plans to remain profitable.

Willie Walsh, the director-general of the International Air Transport Association, an industry trade group said: "The airlines will continue to do everything they can to keep costs in control as much as possible for the benefit of consumers.

"But I think it’s unrealistic to expect that airlines can continue to absorb all of the costs... it's not something we like to do, but it's something we have to do."
