                     RYANAIR WINS LONDON HIGH COURT ACTION

            "DAA AND SRT FOUND TO HAVE COLLABORATED AGAINST RYANAIR"

Ryanair, Ireland's largest airline today (Dec 20) in the High Court in London
won the case for an injunction against SRT (SR Technics) to prevent them (and
the DAA) attempting to force Ryanair to vacate Hangar 1; as well as an order for
specific performance against SRT which must use its best endeavours to obtain a
15 year licence to allow Ryanair to use Hangar 1 on such terms as the DAA may
reasonably consent.

Today's judgment by the Honourable Mr Justice Gray, was critical of both SRT and
the DAA for their behaviour. Amongst other findings in his judgment, Mr Justice
Gray found:

   ."SRT has failed lamentably to comply with its disclosure obligations".
   ."I am doubtful even now if all relevant Board meetings have been
    disclosed (by SRT)".
   ."I am in no doubt at all that SRT was in persistent and clear breach of
    its obligations in relation to obtaining consent from the DAA to a licence
    in favour of Ryanair".
   ."Attempts made in the course of the trial to elicit documents from the
    DAA achieved nothing".
   ."I reject the evidence of Mr Murphy (DAA).
   ."Mr Collier, Chief Executive of the DAA unhelpfully replied that it would
    not be appropriate for the DAA to discuss commercial discussions it might or
    might not be having with third parties. This reply typifies the attitude of
    the DAA to requests for documentary assistance in connection with this
    matter".
   ."The note of the meeting which took place between SRT and representatives
    of the DAA on 10 July 2007 reveals that the proposal at that stage was that
    the DAA would pay SRT EUR5m for relinquishing possession of Hangars 1 and 2.
    The likely tenant at Hangar 1 was to be Aer Lingus. The concluding reference
    in that note is indicative of the collaboration which by then existed
    between the DAA and SRT".
   ."Nor do I accept that Irish Landlord and Tenant Legislation in reality
    prevented the DAA from granting a lease of over 5 years duration".
   ."Damages would not in my view constitute an adequate remedy in the
    circumstances which obtain here".

Welcoming today's High Court Judgement in favour of Ryanair, Chief Executive,
Michael O'Leary said:

    "We welcome both the findings and the decision of Mr Justice Gray to require
    SRT to honour its agreement to provide Ryanair with a 15 year licence to use
    Hangar 1 at Dublin Airport.

    "It is disappointing that Ryanair was forced by the actions of both SRT and
    the DAA to pursue this matter through the High Courts in London. We share Mr
    Justice Gray's concern that neither SRT nor the DAA gave full disclosure of
    their records and documents to the High Court, but even the limited
    disclosure which was provided, conclusively reveals that the DAA was
    collaborating with SRT to throw Ryanair out of Hangar 1 so that the DAA
    could pay SRT EUR5m to regain possession of it, and then lease it to Aer
    Lingus. The fact that Executives of SRT and the DAA have been found to have
    obstructed the Court, and their evidence was rejected, is indicative of the
    low standards of honesty and probity that apply to both companies.

    "The fact that the DAA monopoly has been found to have collaborated with
    SRT, to force Ryanair out of Hangar 1, so that the DAA could lease the
    facility instead to Aer Lingus is I believe indicative of the way that the
    DAA monopoly repeatedly abuses its monopoly power here at Dublin Airport.

    "Ryanair will now consider the detailed judgement of Mr Justice Gray with
    our lawyers. We will be writing to the Minister for Transport and Mr Gary
    McGann, the Chairman of the DAA monopoly, asking that appropriate
    disciplinary measures up to and including dismissal should now be considered
    in the case of Mr Collier, the DAA's Chief Executive, Mr McGowan, the DAA's
    Property Manager and any other executives of the DAA who refused to
    cooperate fully with the High Court in London and who engaged in this
    "collaboration" with SRT against its largest customer, Ryanair."

    "I never cease to be amazed by the extent to which the Department of
    Transport, the DAA monopoly and Aer Lingus are prepared to "collaborate" in
    their attempts to protect and assist each other, while doing their utmost to
    disadvantage Ryanair, Ireland's largest and favourite airline"
