How? The amount of data to cache hourly would be geographically staggering.
Let's say I want to fly out of PDX, and the dream map options are $250, $50, $750, $1000 and $1500. Every hour the system needs to calculate every destination from PDX, from San Diego to Reykjavik to Salem to Naples (both of them) and cache the fares, then do the same thing for every other airport code.
It's daunting - I work in the software field and I'm 100% confident this is why Travelocity dropped the feature.
