Maybe you’ve got a million reward miles you need to use before they expire, but you don’t know which destination to hit first or how to plan your vacation. Or perhaps you’re traveling on business and have several more cities to stop in before you can make it home. How do you figure out the best way to organize your trip? Algorithmia has your solution.

I’ve always regretted not taking a semester to study overseas when I was in college, so when my daughter said she wanted to take advantage of her study-abroad program in Paris, I was thrilled. The cost would be the same as a studying here, except for the airfare. As soon as her departure date was set, I wanted to lock in her award flights. But I wasn’t sure if she would be staying on after her program ended or even if she might be coming back from another city.
