LOS ANGELES — Ticketmaster agreed to settle claims for up to $23 million over a lawsuit affecting about 1.2 million people who, after buying a ticket online, were enrolled in a rewards program that cost $9 a month but never gave them any benefits.
US District Judge Dale Fischer approved the settlement last week.
Plaintiffs’ attorney Adam Gutride said customers will be sent an e-mail Friday with a link to a website where they can file a claim. Each customer can get up to $30. Those who are eligible signed up for the rewards program after buying a ticket at Ticketmaster.com between September 2004 and June 2009. The plaintiffs argued they didn’t know about the fees, which were charged to the credit or debit card used to buy the ticket.
‘‘People have gotten more savvy about these things,’’ Gutride said. ‘‘This was early on. That’s why so many people were duped.’’
The defendants included Ticketmaster and Entertainment Publications Inc.
The lawsuit dates back to January 2007. Under the settlement, the defendants don’t admit any wrongdoing.
The plaintiffs said the affected customers paid about $85 million, or $75.89 each, for the program. It took the average person about eight months to cancel the monthly payments.
