Rick Bartalini Presents is warning consumers after finding hundreds of Journey ticket listings on secondary marketplaces before tickets have even been made available through Ticketmaster, the official provider for the concert.

According to a Thursday news release, 676 listings for Journey’s Sept. 8 performance at Blaisdell Arena were being advertised on secondary marketplaces, including Vivid Seats, SeatGeek and Gametime.

However, the exclusive presale for Hawaii residents is set to begin at 10 a.m. Friday, followed by the public sale at 10 a.m. July 3.

The promoter said the listings are speculative, meaning sellers are advertising tickets they do not yet own in hope of obtaining them later if someone purchases the listing. In some cases, resale sites are advertising seat locations that do not exist inside Blaisdell Arena.

Some listings are advertising tickets with a face value of $77 for as much as $224, an increase of about 188%, according to the promoter. Listings across multiple resale marketplaces are also advertising tickets for as much as $1,451, even though there are no official Journey tickets priced near that amount, Rick Bartalini Presents said.

“This is exactly why I’ve been working with Sen. Chris Lee over the past several legislative sessions to protect Hawaii families from speculative ticket listings, excessive resale markups, and other practices that make live entertainment less accessible,” Rick Bartalini, founder and CEO of Rick Bartalini Presents, said in the release. “What we’re seeing today isn’t hypothetical — it is happening before tickets have even gone on sale.”

Bartalini added that the Hawaii Legislature adopted legislation earlier this year convening a task force to examine how these practices are harming consumers, artists, venues, promoters and the economy, and to develop recommendations to stop it.

Bartalini added that speculative listings can create confusion because consumers may believe resale prices are official ticket prices or assume concerts have already sold out before they have had a chance to buy tickets through authorized channels.

“The artist isn’t setting these prices. The venue isn’t setting these prices. We’re certainly not setting these prices,” Bartalini said.

The release said Hawaii consumers have encountered similar issues before.

Earlier this year, before the Earth, Wind & Fire concert at Blaisdell Arena, more than 1,000 speculative listings appeared on resale websites before tickets went on sale, with markups reaching as high as 800%, according to Rick Bartalini Presents.

Fans are being encouraged to purchase tickets only through Ticketmaster for Journey’s Sept. 8 Hawaii performance, and to avoid buying tickets through unauthorized resale marketplaces before tickets are officially released.
