First, we talk to our partners to find out whether the threat level has immediately changed. If something leads us to believe that the threat level has immediately changed, we have to implement measures to protect ourselves against that threat.
If there is no demonstrable threat, we will monitor the situation. We will first let our colleagues at the affected airport handle their own situation and, at the appropriate time, we will be in touch with them to find out whether they are prepared to share information. Generally, we pay them a visit.
In the aviation world, fortunately, airports do not compete with each other. Consequently, it is much easier in our industry to share information about best practices in security, in terms both of threats and of actions.
