Budget airline Ryanair will offer flights to the U.S. for as little as 10 euros ($13) when it acquires the long-haul aircraft to fly the routes, the airline's chief executive has said.
Speaking at a conference in Ireland, Michael O'Leary said he would offer discount tickets on long haul flights to New York and Boston for 10 euros and flights back to Europe from the U.S. for $10.
The discount price would only cover the cost of the flight, meaning passengers would have to pay extra for their meals and baggage as well as tax.
Not one to shy away from publicity, O'Leary recently described Ryanair as the most "beloved" airline in Europe, despite several high profile customer service disputes.
He once described passengers who forgot to print out their boarding passes (getting charged 60 euros by Ryanair as a result) as "idiots". In a separate incident, he said: "People say the customer is always right, but you know what - they're not. Sometimes they are wrong and they need to be told so."
The flights would leave from up to 14 major European cities to the same number of U.S. destinations, with a full service available six months after the airline has the necessary planes.
"We can make money on 99 cent fares in Europe," he said, speaking at the Irish Hotels Federation conference.
"Not every seat will be 10 euros of course, there will also need to be a very high number of business or premium seats," he added.

However, analysts doubt O'Leary will ever pull off the move, suggesting the airline has plenty of share elsewhere.
"My view is he probably having a bit of fun and he is looking at Norwegian which set up transatlantic flights this summer, and having a bit of a dig at them, "said Robin Byde, transport analyst at Cantor Fitzgerald.
Byde said he does not think Ryanair will ever actually launch low cost transatlantic flights."His real priorities are elsewhere. Italy, France and Germany this year and preparing to receive 175 new Boeing planes," he said.
O'Leary has discussed plans to launch transatlantic flights for years, first mentioning it in 2008, blaming a lack of availability of long-haul aircraft for holding up the move.
Ryanair ordered 175 Boeing 737-800 aircraft at the Paris Airshow last summer, which was Boeing's largest ever firm order from a European airline.
Last year, he said the Boeing order would entice U.S. investors: "Now we've had the order it puts us back in with the growth investors in the States who said, 'Well, you don't have any aircraft coming in, you're an income stock.' We want to be in with a lot of growth shareholders in the United States and remarket ourselves to the growth investors in the U.S."
