What is FlightsFrom?

FlightsFrom.com is a useful website for finding airline routes and flight schedules globally. The idea is being able to explore destination opportunities through non-stop flights from a specific airport. It's a tool to set up your business meeting or weekend holiday based on your timeschedule and your closest airport.

Part of its appeal is that it just makes trips easier to plan; you see the departure times of every non-stop flight in a list.

I always wondered where you could fly direct from a particular airport (Burbank, I’m looking at you) and those answers can be tough to find. Not anymore!

- Rich on tech

Many mainstream sites don’t list low-cost carriers or link transoceanic flights to regionally based carriers that can provide less expensive options. For that, you need a bigger tool kit… (Hint: search by destination airport at FlightsFrom.com)

- The New York Times

Many low-cost carriers airlines prevent their flights from showing up on some of these (read Vayama or Google Flights) third-party travel websites. If you want a chance to view all local departures, try using FlightsFrom.com
