How long will they air interstellar in Imax?

I really wanna watch interstellar in Imax but the good seats keep getting filled up and i wanna watch it in a very good seat so i wanna know if they keep airing the show until tickets slow down then i can just wait until people stop booking to get a good view of the movie, or is there like a time limit (like interstellar will be aired in Tamil theaters until February 20th or something)
