I see.
My other question regarding subcontractors is as follows: Are steps taken to ensure that all of these subcontractors are properly informed of security standards?
I have travelled in a number of airports and I'm not sure they all have the same standards, or that these standards are applied evenly. So then, how do you ensure that the safety of passengers is taken into account when we go for the cheapest option? We try to get the best possible deal as far as security is concerned, when we know that today, security is becoming an increasingly important consideration.
