TKTS is operated by the Theatre Development Fund, a nonprofit organization serving the New York theatre community.
Tickets are available for shows for the current day only .
There are two large signs on either side of the TKTS Booth at 47th Street that list the shows for which tickets are currently available. However, if you don't mind sitting elsewhere in the theatre, this is probably the cheapest place to obtain tickets for most plays and musicals, especially those that have been running for a while.
