Want to know if you're going to be home in time for dinner? Now there's no need to wait around to find out. Thanks to its patented prediction algorithm, Flight Caster is up to six hours faster than airline alerts. (Airlines usually don't put up delay alerts until they're 100% sure, but Flight Caster can give you accurate estimates on probability, so you'll know if there's a 10% or a 90% chance your plane will be held up by bad weather.) Whether you're a professional jet-setter or an infrequent flyer, this little online app is sure to come in handy.
