Thankyou for your comment. I think that you will find AirData is as "serious" as any other system, and provides a good service to its customers. Maybe not run by hundreds of people in a big office, but professional and committed, just the same.
As someone said earlier, an FPS is a planning tool and, as such needs to be easy to use and flexible. Having lots of highly expensive bells and whistles is not always necessary. It depends on who you are and what you are trying to do.
All FP systems are constantly updated to meet the many changes in the industry - and it is how well they do that that is just as important as how "big" they are. You may also be interested to know that the FP suppliers do work together sometimes, to try and make sure that the various "authorities" don't lose sight of what their customers (the airlines) really want.
