- MSN.com

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
