The airline industry is intertwined. Major changes made with backend servers on one airline need to be collaborated with ALL airlines or else information will be missed, misinterpreted, and I don't need to say how disastrous this can be if that happens. This is why airlines still uses dot-matrix across the board. It's not that they don't have the IT-know-how to upgrade, it's because it's not just your company's technology, it has to be the entire global airline industry need an overhaul, and with politics involved, it's becoming an impossible task, and people just fall back to the old mainframe that was setup decades ago. The current airline industry data were designed to be print out on dot-matrix, it's not as simple as just putting in laser printer and convert a few fonts here and there, trust me, if it's that easy they would of done it decades ago.

What I'm talking about is a separate system that simply collect passenger data, create a nice algorithm of analysis, and give management benchmarks to design custom programs that best fit the requirements of each category of passengers. As a IT expert that you claim, you will know this is not hard at all, and has NO direct relationship with legacy airline systems.
