(ANSA) - ROME, NOV 14 - Italy's Antitrust authority has said low-cost carrier Ryanair has committed to refund more than 1.5 million euros to customers who had to pay extra costs for check in. The regulator had opened a practice because the conditions set by the airline on the online procedure could appear misleading on the grounds that they did not inform consumers adequately on how long the service would be available and on the potential cost in case of failure to complete check-in within the deadline set by Ryanair.
