It's unfortunate for Hipmunk to just be turned off despite its founders trying to buy it back: https://skift.com/2020/01/14/hipmunk-co-founders-spurned-by-...

I remember being pretty amazed by its UI back when it launched, but unfortunately has fallen off the last few years.

Flights are hard, and it's why we're staying away from flights at first for my travel startup Wanderium (wanderium.com). Instead we're focusing first on the "long tail" of travel issues: visas, vaccinations, safety, local customs, infrastructure, etc. By aggregating all of this data in a single place and presenting them in a single, personalized experience we think it can save travelers many hours per trip.
