RYANAIR APPEALS COMMISSION'S UNLAWFUL AND POLITICALLY MOTIVATED DECISION
                         PROHIBITING AER LINGUS MERGER

Ryanair, Europe's largest low fares airline, today (Monday, 10th September 2007)
confirmed  that it has  submitted  its  appeal  to the  European  Court of First
Instance  (CFI)  in  Luxembourg   against  the  EU  Commission's   unlawful  and
politically  motivated decision to prohibit its merger with Aer Lingus.  Ryanair
had made an offer of Eur2.80  per share to  acquire  Aer  Lingus  following  the
former national airline's floatation last October.  Ryanair was required to seek
approval  for  clearance  of the deal  from the  European  Commission.  However,
following an 8-month investigation,  the Commission blocked the merger following
pressure  from the Irish  Government  and Aer  Lingus.  As a result,  Aer Lingus
shareholders have suffered a 58% collapse in their interim profits,  and a share
price fall to Eur2.50.

The merger between Ryanair and Aer Lingus would have:

 1. Immediately reduced Aer Lingus fares and eliminated Aer Lingus' unfair fuel
    surcharges, saving consumers over Eur100m. p.a.;
 2. Retained Aer Lingus as a separate brand and continued to operate the two
    airlines separately, thus giving passengers a choice of services;
 3. Retained all of Aer Lingus' profitable routes, including Shannon-Heathrow,
    which Aer Lingus subsequently abandoned;
 4. Reduced Aer Lingus' costs and improved its efficiency; and
 5. Improved Aer Lingus' service and punctuality.

Ryanair is confident that the CFI will overturn this decision because:

 1. This is the first airline merger that was actively opposed by a national
    Government (on narrow political grounds). The Irish Government has now
    admitted that they retained their "strategic" shareholding in Aer Lingus to
    block a hostile takeover "like Ryanair's bid".
 2. This is the first time that the Commission has prohibited a merger between
    two companies which combined will have less than 5% of the EU market.
 3. This is the first time that the Commission has prohibited an airline merger
    and reverses a 20-year policy of encouraging EU airline mergers, having
    previously approved the larger Air France/KLM and Lufthansa/Austrian/Swiss
    mergers.
 4. This is the first time that an EU airline merger offered guaranteed fare
    reductions (and fuel surcharge elimination) of over Eur100m. p.a. for the
    benefit of European consumers.
 5. This prohibition leaves Aer Lingus exposed as a small, peripheral regional
    airline, which cannot compete with Ryanair on price or punctuality from
    Dublin (it has recently pulled off another 5 Ryanair routes from Dublin and
    also announced the closure of its Shannon-Heathrow route) at a time when the
    rest of the European industry is consolidating. Aer Lingus' recent interim
    results saw a 58% decline in Aer Lingus' profits, despite an average short
    haul fare of over Eur90 (more than double Ryanair's average fare of Eur41).

Speaking today in Dublin, Ryanair's Head of Regulatory Affairs, Jim Callaghan,
said:




        "We have filed our appeal with the CFI today asking them to overturn the
        Commission's unlawful and politically motivated decision to block
        Ryanair's merger with Aer Lingus. This merger, which accounts for less
        than 5% of the EU air transport market, was clearly pro-competition and
        would have been the first merger in history to guarantee fare
        reductions, which would have saved European consumers more then Eur100m.
        p.a. The Commission made several manifest errors in its assessment of
        the merger and ignored evidence from Ryanair demonstrating the numerous
        benefits that the merger would bring to consumers and increased
        competition with the high fares Mega Carriers. At the same time, the
        Commission accepted, without question, misleading and factually
        inaccurate submissions from the Irish Government and Aer Lingus, both of
        whom were clearly trying to block the merger.

        "Ryanair also offered unprecedented commitments to the Commission to
        address any possible competition concerns, including giving up more than
        half of Aer Lingus' Dublin-Heathrow slots, as well as over 1,700
        additional weekly slots - several times what has been offered in any
        previous airline merger. However, the Commission refused these
        commitments, preferring instead to block this pro-consumer,
        pro-competition merger for narrow political reasons.

        "The Commission's prohibition of the merger has denied European
        consumers of these benefits and further protects the growing Mega
        Carriers like BA/Iberia/oneworld; Air France/KLM/Skyteam; and Lufthansa/
        SAS/bmi/Star Alliance from a stronger, more competitive Ryanair/Aer
        Lingus group. It has also seen Aer Lingus shareholders lose over
        Eur150m. as the share price has fallen to Eur2.50, considerably lower
        than Ryanair's offer last October.

        "We are confident that the CFI will overturn this decision in the
        interests of consumers and the competitiveness of the industry. As
        always with the European Commission, there seems to be one rule for the
        national Mega Carriers and a completely different one for Ryanair".

Ends.                                   Monday, 10th September 2007
