Back in July 2009 we wrote about a Y Combinator-funded startup called FlightCaster that looks to help you predict flight delays — before the airline even tells you about them. The service looks at air traffic, weather, and a variety of other factors to predict these delays, and the early warning can be very helpful if you need to book a different flight. Today, the startup is announcing that it's been acquired by Next Jump , a large company that powers reward programs for 90,000 companies, including MasterCard's MarketPlace . That seems like a strange fit given FlightCaster's original mission, but things make a bit more sense when you look at what FlightCaster has been up to in the last year.
