ONCE it agrees on a deal for long-haul aircraft.
Chief Michael O'Leary said that the company has prepared a business plan for launching transatlantic flights.
But he said it could be several years before it can get the planes needed.
Mr O'Leary addressed the Irish Hotels Federation (IHF) conference in Meath and outlined that Ryanair would offer €10 flights to the United States, though passengers would pay extra for everything from meals to baggage.
It is understood that the flights will operate from between 12 to 14 major European cities and link up with between 12 to 14 major US destinations.
A FULL SERVICE WOULD BEGIN WITHIN SIX MONTHS OF RYANAIR GETTING THE AIRCRAFT TO DO SO. HOWEVER IT WOULD BE FOUR TO FIVE YEARS BEFORE THIS HAPPENED.
Mr O'Leary praised the Irish government for scrapping the travel tax to Ireland.
He said Ryanair would deliver an extra one million passengers to Ireland as a result, creating an extra €300m in tax revenue through increased tourism spending.
But he urged Transport Minister Leo Varadkar to sell off Irish airports to make them more efficient as had been done in most European countries.
Mr Varadkar hinted that privatising terminals, while maintaining government ownership of the runways and ground areas, could be an option.
