Building activities started six years ago and the terminal was set to go into operation ahead of the European Football Championship in 2008. Its opening date was delayed several times before building activities were halted for almost a year in 2009 amid reports of immense cost overruns.The construction of Skylink resumed last year. Flughafen Wien AG chief Christoph Herbst said he was convinced the terminal will be opened in mid-2012. Herbst added overall expenditure will not be higher than 800 million Euros.
