Hmm. I think this is a pretty shallow take. My experience from the airline industry is that the vast majority of systems classified as flight safety critical are not connected to the internet, or large networks at all. Which is good. But unless we want to drastically change how airlines operate, the rest need to be online. Today, you can purchase a ticket (or rebook an existing one) on your phone really close to the departure time. When that happens, a gazillion interconnected systems, across legal entity borders, need to cooperate to take you (and your luggage) to the destination. To put all of this in a large non-internet network seems pretty pointless. If we wanna go down that route, the only real "security improvement" I can think of is to dismantle the digital systems and go back to paper. Like Ryanair did during this incident. Handwritten boarding passess, verified against print-outs of passenger manifests.
