I hope this isn't too off-topic, but the "weird" encoding is is just URL-safe base64 (see https://docs.python.org/2/library/base64.html#base64.urlsafe...).

My common use case is "I will spend $X to go anywhere for under Y days any time in the future" and I haven't found a service that makes this easy.
Kayak's "explore" page is the closest I've found, but they rarely have the cheapest flights listed and have no way to set duration. Has anyone found a better solution?
