Why I Built FlightList & Solved My Own Problem

Why I Built FlightList

❝As someone who works remotely & travels frequently, I always book one way flights and I'm flexible on my departure dates. I look for the best deals. Most sites require you to enter a specific departure date and clutter the page with uneccessary options, images and ads. I wanted something simple and minimal which allowed me to search by departure date range and display a list of flights with the ability to filter according to my needs. I built FlightList to solve my own problem and help other travelers who may have the same frustration. It's how I imagine a flight booking site should be.❞
