All the flights possible

I am often frustrated when trying to fly from one obscure place to another obscure place with as few stops in between. Most flight sites want you to keep the journey on the same airline. What I want is “show me ALL the flights from this airport,” and I’ll figure out a route on my own. No surprise, there’s a site for that, called appropriately enough I can assemble a route, sometimes with obscure airlines, that won’t show up elsewhere. — KK
