Budget airline Ryanair today out forward a complaint to the European Commission, reports Reuters.

The complaint was against Dublin Airport Authority and comes as a result of DAA's plans to build a second terminal.

Ryanair although in favour of a second terminal, has made the complaint on the basis that it believes that DAA would not be able to operate at budget.

According to Reuters, Ryanair said in a statement: Ryanair ... will submit a complaint to the European Commission against the DAA for abuse of its monopoly position at Dublin Airport, which has resulted in the T2 costs rising fourfold even before planning has been applied for.
