Nice idea! I travel quite a bit and can see how this could be useful for big trips. It would be great to see this for multi-stop flights as those are the most expensive tickets I buy. But I understand that it becomes quite a bit more complex then. UX-idea: when choosing a return flight and picking a departure date in the future, then the return date could automatically become the day after. So that the user does not have to move ahead a few months two times.

Doesn’t Google Flights already have this functionality?
