Vienna airport is suing the Austrian government in an attempt to recover the costs of the US$34 million rebuilding work needed to prepare the airport for the country's membership of Schengen. The agreement removes border controls between the signatory EU states. But as not all EU countries are signed up to Schengen, the airport has to provide three separate areas to process Schengen, non-Schengen EU and non-EU arrivals. Austria is due to join Schengen in July but may delay till October.
