I've used the TKTS booth numerous times post-COVID, and I've never waited more than 15 minutes to get to a window. I usually go 60-90 minutes prior to curtain rather than queuing up before it opens. I've found that lines are more manageable as it gets closer to showtime, that better seats are released later on, and I've had no complaints.
Each time I've gone recently, the attendant has asked for my price range and accommodated my specific request for aisle seats. Most recently, for OH MARY! (with John Cameron Mitchell in early March), I got fifth-row aisle seats about an hour before showtime.
"You travel alone because other people are only there to remind you how much that hook hurts that we all bit down on. Wait for that one day we can bite free and get back out there in space where we belong, sail back over water, over skies, into space, the hook finally out of our mouths and we wander back out there in space spawning to other planets never to return hurrah to earth and we'll look back and can't even see these lives here anymore. Only the taste of blood to remind us we ever existed. The earth is small. We're gone. We're dead. We're safe."
