As reported by Playbill.com today:
The world premiere production of Harry Potter and the Cursed Child, currently running at the West End's Palace Theatre, will release another batch of tickets for performances in early 2018.
Around 75,000 tickets will go on sale January 23 at 11 AM GMT (6 AM ET), for performances February 7 to April 29, 2018. On past experience, the online queue is likely to stretch to many thousands, and the tickets will no doubt sell out on the day they are released.
