I am flying this Friday so I will make sure to test it out. That's a pretty steep price for the iPhone app though... if you guys can recommend me alternative routes then that would be worth paying for, but at the current stage I don't see myself paying for an app just to check if my flight will be delayed or not.<p>When I was a consultant, I used to travel every week. What irritated the heck out of me is these in-route weather conditions. So for instance, if I am flying from Dallas to NY, and there's bad weather somewhere in the middle, they will cancel the flight. If you can recommend me to get on a flight that will go around the problem (such as Dallas -> Miami, Miami -> NY), then it would be really useful. But this is probably only useful for business travelers since casual travelers probably won't be willing to shell out the extra airfare.
