The current estimate used for average ticket price in the U.S. is the same as 2008 - $7.18. However, there is usually a revision completed early in the following year (2010) that will give a more accurate average price. I expect it may be around $7.40, although it may not go up very much due to the current economic situation in the U.S.. There are several websites that track the movie market that can give you good estimates on ticket prices (boxofficemojo and thenumbers to name just two.)
