One search feature I wanted was a way to look up a list of all flights leaving an airport on a certain day.
In the early stages of vacation planning, it’s be fun to see a list of all possible direct flights to evaluate my options, but the use case of doing flight searches with an unknown destination isn’t too common. Basically, i want to be able to browse flights like a bus schedule and just see what the possibilities are from a particular start point
Google Flights does this really well - just leave the destination empty or use something generic, like Europe/USA. I do this all the time to find new places to go to.
