                      RYANAIR DELAYS ADDITIONAL AIRCRAFT
   AT EAST MIDLANDS AND PISA BASES FOR A PERIOD OF TWO MONTHS DUE TO DELAY IN
                               BOEING DELIVERIES

Ryanair, Europe's No.1 low fares airline today (Tuesday, 20th December 2005)
announced a number of changes to its flying programme during January, February
and March 2006 to accommodate the late delivery of new aircraft from Boeing, and
Ryanair's decision to retire the existing fleet of 737-200's on schedule at the
end of December. These cancellations will reduce Ryanair's passenger traffic by
approximately 100,000 passengers per month during January, February and March
and will reduce the overall passenger traffic in the current fiscal year to just
under 35 million passengers.

As a result of a strike in Boeing during September and October, all of Ryanair's
aircraft deliveries this Winter are being delivered approximately 1 month after
their scheduled date. Ryanair has been able to meet this 4 aircraft shortfall
during October, November and December by extending the flying programme on a
number of older 737-200 series aircraft due for retirement. It is not possible
to extend the use of these aircraft beyond the end of December 2005, as the
aircraft have been sold and the pilots have been retrained on the 737-800's. The
airline has therefore decided to trim its schedule temporarily through January,
February and March 2006. Planned capacity will return to normal with the
delivery of the last 4 aircraft from Boeing during the month of April 2005.

These aircraft constraints will result in the following schedule changes during
the first 3 months of 2006:

   -The cancellation of 200 rotations per month (approx. 1% the total flying
    programme) during January, February and March.
   -The delay of the launch of the second aircraft at the Nottingham East
    Midlands base from 7th March to 5th April.
   -The delay of the launch of the second aircraft at the Pisa base from 12th
    January to 4th April.

All passengers currently effected by these cancelled flights or the 2 month
delay in new flights at the East Midlands and Pisa bases will be notified at
least 3 weeks in advance of the original date of travel and will be offered
either re-accommodation on an alternative Ryanair flight, re-accommodation on
the new routes from East Midlands and Pisa when launched, or a full refund of
their air fares.

Commenting on these cancellations during the first 3 months of next year,
Ryanair's Deputy Chief Executive, Michael Cawley said;

    "We very much regret having to reduce our schedule to allow for the late
    delivery of new aircraft from Boeing and the planned retirement of our older
    737-200's in December. These aircraft have already been sold. We apologise
    sincerely to all our passengers who may be inconvenienced by these schedule
    changes, and we look forward to welcoming them on board the new flights from
    East Midlands and Pisa when the new aircraft are delivered and based there
    during April 2006.

    "These schedule changes will not effect Ryanair's profit guidance for the
    fiscal year ended March 31, 2006."
