Got noticed around my office this morning. There seems to be a glitch in their system where if you do a "multi-flight" trip on Priceline using the following steps, you end up with a price of around $150.
- NYC to Milan in mid November to mid December, ideally leaving mid-week.
- Prague to Tokyo about a week later, with a stopover in Paris.
Not sure what exactly the constraints are, but you can sub out a lot of cities and get a similar deal as long as they're served by the same airlines (Air Italia for the first leg and Air France for the second leg)
Probably a glitch, but Priceline has a history of honoring booked trips when stuff like this slips by them.
