The Australian Competition and Consumer Commission (ACCC) launched proceedings in the Federal Court against Webjet Group (ASX:WJL) subsidiary Webjet Marketing, citing "false and misleading representations to consumers about flight prices and bookings," the regulator said in a statement Thursday.

Webjet Marketing purportedly posted on the Webjet website, app, marketing emails, and social media about the minimum price of flights for the period November 2018 to November 2023 while omitting or minimizing information regarding compulsory fees ranging from AU$34.90 to AU$54.90, according to the statement.

Further, the ACCC claims that the company breached relevant laws by sending a booking confirmation email after taking payment for a completed flight booking when in fact, in respect of 382 bookings, it had not booked the flight with the airline.

In a Thursday filing with the Australian bourse, Webjet Group said it takes its compliance obligations "extremely seriously," adding that it has cooperated with the ACCC even before the launch of the proceedings and has implemented changes to its pricing and fee disclosures.

The company's shares were down almost 7% in recent Thursday trade.
