The site is easy to use and quickly identifies and sorts an array of possible flight options. The first couple of times, I compared results with several other airfare ticket websites, and reached the same conclusion: JustFly doesn't seem to miss any combination of airlines and flights to reach my destination. Except, Southwest is not included on any of the airfare search sites. I've used it enough now that I just go straight to JustFly. I had seen the same flights on the other sites at around the same price, but it took longer to find them.
