Question: How do I know what tickets are available at TKTS?
Answer: You won't know in advance. TKTS only sells day of show tickets. (The exception is the TKTS at South Street where matinee tickets must be bought the day before.) Many theaters don't release their unsold tickets to TKTS until the morning of the show. In fact, some shows may give TKTS more tickets to sell after they open.
