My iOS app FlyOrDelay is out in the Apple App Store here. It shows airport delays, not flight delays, but this is the time of year where there will be a lot of airport delays. Lightning at MCO? Ground stop. Thunderstorms at DFW? Ground stop. Windy at ORD? Departure delay. You get the point. At $.99, it’s cheap. Go get it now. Let me know how you like it.
