Dublin Airport will refund nearly 4,500 customers who were overcharged during sales earlier this year. It was flagged to the Competition and Consumer Protection Commission, which notified the airport operator. Under the Consumer Protection Act 2007, it is against the law to provide incorrect or misleading information to consumers about price promotions. Brian McHugh, the head of the CCPC has welcomed DAA's decision to refund customers. All calls to the CCPC helpline are screened for potential breaches of consumer protection law and drive our enforcement and compliance activities."
