Ballet experience with the 30 under 30 promotion! I recently attended performance by the New York City Ballet through their 30 Under 30 promotion, and it was an incredible experience! The opportunity to see such world-class dancers at an affordable price is something I’d highly recommend to anyone under 30 living in or visiting NYC. experience world-class ballet performances at an affordable price. Here’s how it works: You sign up for free on the NYCB website by verifying your age with a valid ID. Once registered, you get access to specially priced tickets (usually around $30) for select performances throughout the season. You can purchase up to two tickets per show, but the second person must also be under 30. The seats available vary, but they’re usually in great sections of the theater.
