Several people are saying that this is already a free service from airlines and so this won’t work. Not quite. 1. Airlines tend to estimate delays optimistically. They don’t want to look bad. I’d rather rely on a third-party. 2. Airlines offer very bland services. This service could offer a better experience. For example, will airlines tweet my delay? Or send me a Facebook update? Or text me? Or call me? There might be useful options here that airlines are not providing. 3. Airlines might not notify my friends and family. Generally, notifying me is less important than notifying them. If I get notified my flight is delayed but I am in the air and have no internet then the notification is pointless. This service could notify other people that I add to my flight’s notification list. The fact that the airlines provide this service is not a sign that this won’t work—rather it’s a sign that this is something valuable. You can use the airlines’ service as a starting point and then build this into something a lot better.
