I have to say that I find this app to be a GREAT tool, and far, far better than using the mobile version of Flyertalk on on iPhone. I don't begrudge the ads either, as websites have to make money somehow, and Flyertalk follows a publishing model. Having said that, I echo the comments of others and would gladly pay up to $4.99 for an "ad free" version.
Nice job on a first version!
