AKs deep in a tourny

I think I have lost more money with AK in my all ins then with any other hand. How foldable is it deep in tournies, knowing that the only hands a player pushes with is going to be a pair where they are a slight favorite or AK.... which you have. This is my last significant hand in a stars tourny where i thought i was going to win... is AK foldable here seeing that i have a healthy chipstack?

Background- only 25 players left, no good money till final table. Average stack around 50k.

He had 99... which i did not expect, but im still a slight dog to his hand. I am growing a great disdain for AK.
