The Federal Trade Commission on Tuesday said it will soon require hotels, vacation rental platforms and live event promoters to disclose any fees up front when they list prices. The FTC said consumers often see advertised prices for hotel rooms, short-term rentals, and tickets to sporting events and concerts only to be surprised later by so-called “junk fees,” including resort fees, cleaning fees, processing fees and other extra charges. “People deserve to know up front what they’re being asked to pay without worrying that they’ll later be saddled with mysterious fees that they haven’t budgeted for and can’t avoid,” FTC Chair Lina Khan said in a statement. The rule is scheduled to go into effect in 120 days. Ticketmaster said Tuesday it supports the new rule. “Ticketmaster has long advocated for all-in pricing as a nationwide industry standard, and we’re pleased to see the FTC mandate the necessary changes to make ticket-buying more transparent for fans,” the company said. The Associated Press left a message seeking comment Tuesday with the American Hotel and Lodging Association. Four of the FTC’s five commissioners voted to approve the rule.
