Friday's armed raid has concentrated minds on the issue of future security at the airport. Several significant changes are expected to follow, but before changes can be introduced, Aer Rianta and the Garda - jointly responsible for airport security - have to overcome an occasionally difficult relationship.
Senior figures in both organisations say that relations at senior level are good, but co-operation on the ground is not always amicable.
The two organisations have been considering ways to improve security for the past few months, but have yet to reach agreement on a number of key issues, including a Garda plan to boost the force's presence at the airport Garda station.
Despite Friday's raid, in which an armed gang stole more than £100,000 from the airport bank without being challenged by any armed security personnel, both Aer Rianta and the Garda rejected accusations of an unprotected airport.
However, it appears that significant changes will be needed, including a specific effort to tackle tension between certain members of both the Garda and Aer Rianta security staff.
The airport police are employed by Aer Rianta and since the passing of the Air Transport Navigation Act, have acquired extensive powers, including the power of arrest.
Some gardai at the airport have become concerned at this and have spoken of their role being usurped by the airport police.
Nevertheless, discussions about airport security have been ongoing, but agreement on Garda plans to boost the force's presence at the airport has not happened.
Gardai have suggested that staffing at the Garda station in the airport buildings should be increased to 20 members of garda rank and four sergeants, which they say would be a considerable increase on the existing presence.
But an Aer Rianta source acknowledged that the company had not so far agreed to this.
However, he acknowledged that all aspects of security at the complex would now have to be reviewed.
The placing of a barrier outside the airport Garda station, which is situated beside the old terminal, has become a source of tension. Some gardai claim members of the public are hindered in gaining access to the station.
A meeting between both forces is likely to take place shortly to iron out differences and consider proposals for the future enhancement of airport security.
Aer Rianta pointed out on Friday that airport police are unarmed and have no access to arms and consequently were not in a position to tackle the three raiders.
Referring to the apparent absence of an armed Garda unit in the vicinity of the airport, a Garda spokeswoman said she could not comment because it was an operational matter.
Meanwhile, the Garda at Santry continued their investigation into the robbery and were examining three vehicles used in the raid for evidence.
The video footage of the raiders is not expected to yield any significant information.
