Anyone know the cheapest airfare from USA (im from Mason City, Iowa) to overseas Philippines, Manila online?

The cheapest I can find right now is about $1,600 RT MCW (Mason City, Iowa) - MNL (Manila, Phils.) for travel in August. However, I would suggest you keep on checking the Internet - sites like travelocity, priceline.com, etc. - coz usually by April-May, they discount air fares.
