Ryanair is offering to send free text alerts to passengers whose flights are delayed for over 90 minutes.
The airline is asking customers to provide their mobile phone number in order to avail of the service.
Passengers who experience flight delays of 90 minutes or more will receive a text message advising them on the likely duration of the delay and their new departure time.
The new service is an addition to Ryanair's existing email/text and website passengers communications which was developed in partnership with Sentient.
Ryanair spokesman Stephen McNamara said a study had found an estimated 95 per cent of airline passengers carried mobile phones when travelling. "Our new system will ensure passengers are kept fully informed during periods of mass disruption, such as bad weather, air traffic control strikes or airspace closures."
