Ryanair is to be listed on the Nasdaq stock exchange from the opening of trade tomorrow morning.
The airline's chief financial officer, Howard Millar, said: "This listing will bring greater visibility and wider appeal to both institutional and private investors worldwide."
Ryanair Holdings currently has a total market capitalisation of $12.3 billion. Some $5.6 billion of this is traded on the Nasdaq Securities Exchange.
The carrier is planning to operate some 134 Boeing 737-800 aircraft by March 2007, which will carry 42 million passengers each year.
The fleet will be expanded to include a further 147 aircraft as part of Ryanair's bid to double passenger numbers to 84 million in 2012.
