At least 200 European airline websites are misleading the consumer, a study by the European Commission has found.
Websites are failing to show taxes and charges, and refusing to advertise the lowest fare prominently, according to the report.
The Commission has refused to name any airlines involved in order to give them time to improve their service.
Last month, a Spanish watchdog said it had found misleading information on seven websites, including Ryanair.
