                 RYANAIR CELEBRATES 100 YEARS OF POWERED FLIGHT
                         100,000 SEATS AT 1903 PRICES!
                           FLY FOR JUST 10 SHILLINGS!

Ryanair, Europe's No.1 low fares airline, today (16th Dec 03) announced 100,000
Seats at 1903 prices of just 10 shillings (50p) (inc taxes) to celebrate 100
years of powered flight on 17th December 03. The special celebration of the
achievements of Orville & Wilbur Wright will be available on 75 of Ryanair's
routes throughout Europe and passengers wanting to grab a bargain and share in
the celebration can book on Wednesday 17th December 03 only- the 100th
anniversary of the Wright Brothers first ever powered flight.

"Announcing the celebration, Ryanair's Deputy Chief Executive, Michael Cawley
said:

"100 years ago tomorrow, Orville & Wilbur Wright took to the skies in the
world's first-ever powered flight. Little did they know they would be changing
the way people travel forever. In Europe, Ryanair have carried on that
pioneering spirit, and continue to revolutionise air travel by making it
affordable to millions of ordinary consumers.

"Today flying with Ryanair can be cheaper than a taxi to the airport, and we
think it is a fitting tribute to Orville & Wilbur to continue what they started,
and to celebrate 100 years of powered flight with 100,000 seats at the 1903
equivalent of Ryanair's average fare of GBP32, which means prices of 10 x
shillings (50p) (inc. taxes)!

"This special celebration offer is available for booking on 17th December 03
ONLY exclusively at www.ryanair.com and is available for travel throughout
January 2004. Join in the celebration and grab a bargain at 1903 prices!"
