Backstreet Boys Las Vegas Sphere tickets are cheaper than ever. Get them now

Getty Images Way back in 1999, when the Backstreet Boys were at the height of their powers, ticket prices started in the $30 to $40 range. Somehow, 25 years (and significant inflation) later, we found seats to see Nick, Howie, AJ, Kevin and Brian’s ‘Into The Millennium’ residency live at Las Vegas’ Sphere for dollar amounts that would have almost made sense…at the turn of the Millennium. Based on our findings, some tickets to see one of the ’90s definitive boy bands this weekend are going for as low as $70 including fees on SeatGeek at the time of publication. Other concerts of theirs from Aug. 13-15 have inventory starting anywhere from $83 to $147 including fees.
