          RYANAIR ANNOUNCES IN FLIGHT MOBILE ACCESS FOR ALL PASSENGERS

    New venture with communications pioneer OnAir will enable Ryanair's 42M
                   passengers to keep in touch on all flights

                INFLIGHT PHONE SEAT SALE 1M SEATS - DIAL GBP9.99!

Ryanair, Europe's largest low fares airline, and OnAir, the leading onboard
passenger communications provider, today (Wednesday, 30th August 2006) announced
a deal that will see Ryanair's entire fleet of Boeing 737 aircraft fitted with
OnAir's onboard mobile communications solution. The announcement will make
Ryanair the first European airline to offer Europe-wide mobile telephony
services during flights across its entire fleet of aircraft to all passengers
via their own mobile phones and smartphones.

The deal means that from mid 2007 (subject to relevant regulatory approval)
Ryanair's passengers will be able to call, text and e-mail using their mobile
phones, BlackBerrysTM and TreosTM at rates which will mirror international
roaming charges. OnAir intend to fit 50 Ryanair aircraft during the second half
of 2007, with the remainder of the fleet receiving installations from early 2008
onwards. Mobile OnAir will be offered on all Ryanair flights across Ryanair's
network of more than 360 routes serving 23 countries across Europe. Ryanair will
be the first European airline to offer this mobile telephony to all passengers
on all of its 200 plus aircraft fleet.

Developed by inflight communications specialist OnAir, Mobile OnAir uses
advanced lightweight onboard technology to allow passengers to make and receive
calls, exchange SMS messages and connect to e-mail via satellite broadband links
and a ground network to be supplied by OnAir's telecoms infrastructure partner,
Monaco Telecom.

OnAir's solution allows mobile phone operators to charge passengers using Mobile
OnAir at rates in line with current international roaming charges on passengers'
normal monthly bills. Ryanair will receive a commission from OnAir on call
revenues generated by passengers on board its aircraft.

Announcing the new service initiative, Ryanair's CEO Michael O'Leary, said:

        "This is another revolutionary passenger service initiative from
        Ryanair. In addition to offering our customers the lowest air fares and
        youngest fleet of aircraft, Ryanair will soon enable passengers to use
        their mobile phones and electronic communications devices in the air,
        just as they do on the ground. That means they will be able to pass on
        the good news to workmates, friends and family that they are travelling
        on another on-time flight with Europe's most punctual airline.

        "This is a win-win for Ryanair, OnAir and most importantly our
        customers. The revenues generated by onboard mobile telephony will
        reduce our costs and help us to keep offering the lowest fares in Europe
        while at the same time doubling the size of our operation over the next
        five years as we grow to carry 80M passengers annually by 2012. To
        celebrate this new service, we are offering 1M seats from the UK to
        Europe for just GBP9.99*. Passengers should dial up their low fare seats
        immediately on www.ryanair.com as fares this low will not last long ".

George Cooper, CEO of OnAir, added:

        "We are delighted that Ryanair is to become the first carrier to install
        Mobile OnAir throughout its fleet. Not only is Ryanair one of the
        world's most innovative airlines, but the deal is also a strong
        endorsement of the all round capability of our solution for both Boeing
        and Airbus aircraft".
