I have been using SkyScanner since January 2014. SkyScanner works with booking all different types of airlines. I've notice that SkyScanner can be used in a good way or a bad way. Depending on where you are located, and the time of year, you can find cheap flights on SkyScanner going to different places all over Europe. Some flights may have long layovers, and other flights may be direct. When I flew from Naples to Luxembourg it took me about 5 hours. Even though, I had a layover it wasn't that long. As long as you plan well and do not fly with a lot of layovers, this is a good site to use.
