In this episode of Masters of Data, we buckle up and explore the staggering technological complexity behind the airline industry, from managing IoT devices across global fleets to navigating the data chaos of mergers and acquisitions. We dig into the delicate balance airlines strike between aging legacy systems and risky upgrades, and why getting that wrong isn't just costly but potentially catastrophic. We also look at how forward-thinking airlines are turning operational logs into real business wins, all while safeguarding the mountains of sensitive passenger data they collect every day.
