The reservation for the Avengers : Endgame is on sale fore 2D showtimes now.
In case of IMAX and 4DX, it would start from 18:00 on 18th, this Thurs.
We recommend that you book after 24th though it is the first day of release because many show times on 24th are almost sold out.
Many good seats are available from 25th next week.
The special screening showtimes such as IMAX or 4DX of first few days would be sold out very fast, even in 20 mins.
That would be a different meaning of war from the war of Avengers…
