              HAPPY BIRTHDAY RYANAIR - 20 YEARS OF LOWERING FARES
                       
                        Seat sale of 200,000 seats at 99p
                     over 100 times cheaper than 1985 fare!

Ryanair, Europe's No. 1 low fares airline today (Thursday, 26th May 2005)
celebrated 20 years of delivering low fares to Europeans. Ryanair was founded
this week in May 1985 and to mark the occasion is launching a sale of 200,000
seats sale at 99p* - over 100 times cheaper than the lowest 1985 fare of 
GBP99.99.  The offer begins today and ends midnight Thursday, 2nd June 2005.

Speaking today, Ryanair's CEO Michael O'Leary said:

      "This week 20 years ago, Ryanair was founded and was soon selling never
      before seen fares of GBP99.99 - a totally radical move in an industry that
      was charging well over double the price.
      
      "Since then, while the price of a pint of beer has increased threefold
      and the price of property has increased by fivefold - Ryanair has made
      its tickets 100 TIMES CHEAPER. To celebrate this anniversary we are
      launching a sale of 200,000 seats at 99p* - over 100 times cheaper than
      our 1985 fare!
        
      "To take advantage of our time busting offer with wide availability for
      travel in June, book now on www.ryanair.com as demand for these summer
      seats will be huge."
