Online travel agent booking.com has offered to scrap a practice which prevents hotels from giving discounts to its rivals, in a bid to end investigations by competition authorities in France, Sweden and Italy, the European Commission said on Monday.

Such so-called parity clauses in contracts between online booking sites and hotels are common in the industry and have led to complaints by competitors and scrutiny by regulators across Europe who are worried that they may dampen competition and hurt consumers.

The Commission, the antitrust enforcer in the 28-country European Union, said it was coordinating the national probes and that it was not conducting its own investigation. Third parties have until Jan. 31 to provide feedback on the concessions.

“Booking.com has proposed to abandon the parity requirement in respect of prices which the hotel makes available to other online travel agents,” the Commission said in a statement.

It said however that booking.com, part of U.S. company Priceline Group Inc, could still have clauses in their agreements with hotels preventing them from offering discounts or lower rates on the hotels’ own websites.
