        RYANAIR TO APPEAL UNLAWFUL EU DECISION TO COURT OF FIRST INSTANCE

              CALLS ON AER LINGUS TO SCRAP UNFAIR FUEL SURCHARGES

               LAUNCHES 2M SEATS FOR EUR10 (incl. taxes & charges)

Ryanair, Europe's largest low fares airline today (Wednesday, 27th June)
confirmed that it would appeal the EU Commission's unlawful decision to prohibit
the merger with Aer Lingus to the European Court of First Instance. Ryanair
expressed confidence that this prohibition will be overturned because;

 a. -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.

 b. -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 merger and the Lufthansa/
    Austrian/Swiss mergers.

 c. -This is the first time that an EU airline merger offered guaranteed fare
    reductions of over EUR100m p.a. for the benefit of consumers.

 d. -This prohibition leaves Aer Lingus exposed as a small, peripheral loss
    making regional airline which cannot compete with Ryanair on price or
    punctuality from Dublin (it has recently pulled off another 5 Ryanair routes
    from Dublin) at a time when the rest of the European industry is
    consolidating. Aer Lingus lost EUR70m last year despite an average short
    haul fare of over EUR90 (more than double Ryanair's average fare of EUR41).

Ryanair confirmed that the prohibition would be bad news for Aer Lingus'
passengers who will continue to suffer higher fares, unnecessary fuel
surcharges, poor punctuality and repeated strikes (such as the latest staff walk
out just two weeks ago).

Ryanair also criticised the continuing failure of the Board and Management of
Aer Lingus to deliver value for its customers or shareholders;

 1. -Aer Lingus fares are rising (in line with its IPO strategy).

 2. -Aer Lingus has recently raised its unjustified fuel surcharges for long
     haul passengers.

 3. -Aer Lingus has wasted almost EUR20m of shareholders' funds to oppose a bid
     of EUR2.80 per share when its share price is just EUR2.60.

 4. -Aer Lingus has ordered new long haul aircraft recently when prices are at
     an all time high.

 5. -Aer Lingus has (since Ryanair's offer) pulled services from 5 more Ryanair
    routes because it is unable to match Ryanair's punctuality or prices.

 6. -Aer Lingus has supported the DAA's proposed T2 which will double passenger
    charges at Dublin and substantially increase Aer Lingus' costs.

 7. -Aer Lingus has presided over a decline in the share price from over EUR3.00
     to just EUR2.60 yesterday - significantly below Ryanair's offer price.

Aer Lingus' actions in recent weeks has damaged its cost base and destroyed
significant shareholder value. It would appear that the Board of Aer Lingus is
more interested in looking after its own interests and those of the Irish
Government than it is in lowering airfares or increasing its share price. In its
defence documents, Aer Lingus claimed that Ryanair's offer of EUR2.80 per share
"devalued Aer Lingus". How does it now explain or justify a share price as low
as EUR2.60, significantly less than Ryanair's offer?

Speaking today in Dublin Ryanair's CEO Michael O'Leary said;

        "Aer Lingus claimed yesterday that the EU Commission's prohibition is
        'another boost for Aer Lingus and for consumers'. This is nonsense. Aer
        Lingus' share price is now significantly below Ryanair's EUR2.80 offer
        which means that their shareholders are losing out. The fact that
        consumers will be denied the Ryanair guarantee of lower Aer Lingus fares
        and the elimination of fuel surcharges means that they will suffer a
        penalty of over EUR100m p.a.

        "Aer Lingus is continuing to waste shareholders' money by ordering new
        aircraft at the top of the cycle, by supporting expensive T2 facilities
        at Dublin airport which will double their costs and by wasting almost
        EUR20m of shareholders funds to oppose Ryanair's EUR2.80 offer. This
        waste has been reflected in their falling share price.

        "We call on Aer Lingus to lower their fares and scrap these unfair fuel
        surcharges and at least deliver the same value to consumers that
        Ryanair's offer would. In the mean time Ryanair will continue to grow,
        will continue to offer lower fares and will continue to beat Aer Lingus
        on price and punctuality. We look forward to the European Courts
        overturning this unprecedented and unlawful prohibition".
