Schengen failure would cost airports a fortune

Bringing back air border controls would have drastic impact
Europe’s airports would have to spend hundreds of millions of euros on redesigning terminals if the Schengen zone for passport-free travel collapsed, the airport association ACI Europe warns.
Such a development, a possibility as the free-travel agreement comes under increasing pressure due to the refugee crisis, would create major congestion and extra costs, ACI Europe says.
The Schengen zone, which was created more than 30 years ago, resulted in terminal designs that separate Schengen and non-Schengen zones.
Any moves to reinstate air border controls between Schengen states would have a drastic impact, the airport association cautioned. Restructuring airports could cost hundreds of millions of euros for the largest airports.
