Tickets at box office 1-2 hrs before a show (Studio 54) Lifespan of a fact

Trying to filter through the rush seating but this isn't about rush seating, wondering the likelihood of getting any type of seating at the box office at Studio 54, 1-2 hours before an evening show.

Issue: In case there are delays or cancelations I can't purchase the tickets online before I arrive. I have a connecting flight that flies into LaGuardia arriving ETA 4:10pm. Should there be no delay, possible 1hr 30min bags and commute, 30 min hotel, 10min to Box office, Let's say 6pm arriving at the box office. Is it likely to be able to get single tickets for the play for that evening? I'm not even sure if telecharge will let me purchase tickets an hour before a play. Doesn't help that Studio 54 box office doesn't have a phone number

Any advice is helpful. Thanks!

This show is frequently available through TKTS. When faced with the same question, I checked TKTS live app as to availability and seeing there was, went there. My backup plan was to go to the box office. This was on a Saturday night a few weeks ago.

TKTS at Lincoln Center almost never has a line and is as close to Studio 54 as Times Square is.
