Mobile ticketing platform Atom Tickets has added three new theatre partners to its portfolio.

B&B Theatres, Flix Brewhouse and Southern Theatres will collectively add 891 more screens to the Atom platform, bringing the total up to more than 18,500 screens across North America.

Atom Tickets allows users in North America to pre-order movie tickets and concessions, while the platform also provides moviegoers the option to watch trailers, read reviews and coordinate movie outings with friends while allowing each person to pay separately.

Top chains AMC Theatres and Regal Cinemas are among those added to the list with the three new partnerships, which will be available before the end of the year.

Flix Brewhouse is a specialised chain that incorporates microbreweries into cinemas and will add four locations and 33 screens to Atom next month. Southern Theatres will add 40 locations and 458 screens under its Movie Tavern, Amstar Cinemas and The Grand Theatres brands. While B&B Theatres will add 400 screens across 50 locations in seven different states.

The expansion comes off the back of the Atom platform officially launching on 267 screens in Bow Tie Cinemas locations, across six states.

“We’re incredibly proud to have officially launched our partnership with Bow Tie Cinemas, and we’re excited to welcome B&B Theatres, Flix Brewhouse and Southern Theatres to the Atom Tickets family,” said Ameesh Paleja, Atom Tickets co-founder and chief executive.

“With each new location, the Atom platform brings a more convenient, more social experience to millions of movie lovers all across the country.”

Through Atom’s social invite feature, users can purchase their ticket and also invite friends to go to the movie without paying for them. This process allows groups to easily reserve seats together – a crucial benefit for highly anticipated box office releases.

During the summer, Atom Tickets and the telecoms company’s T-Mobile Tuesdays, which provide North American customers with free gifts and chances to win prizes, launched a blockbuster marketing drive. The films included The Hitman’s Body Guard, Wonder Woman, Transformers: The Last Knight and War of the Planet of the Apes.
