The ease of use! I can't say enough about how easy it is to work with this software. From creating an account to starting my first flight there isn’t much that you need to know to get started using Fl3xx. There are plenty of resources within their support section as well as online forums where questions arise. They also have some free in-flight training videos available through YouTube which helped me understand many features of their product quickly. Nothing really stands out at this time but they seem very responsive to any issues we had while implementing our system into the airline's operations. We were able to automate processes such as dispatching flights and tracking crews without having to manually enter data each day. It has been great helping us streamline these tasks so that we can focus more on improving customer service instead of paperwork.
