More Airline Outages Seen As Carriers Grapple With Aging Technology

An anonymous reader writes: Airlines will likely suffer more disruptions like the one that grounded about 2,000 Delta flights this week because major carriers have not invested enough to overhaul reservations systems based on technology dating to the 1960s, airline industry and technology experts told Reuters. Airlines have spent heavily to introduce new features such as automated check-in kiosks, real-time luggage tracking and slick mobile apps. But they have avoided the steep cost of rebuilding their reservations systems from the ground up, former airline executives said. Scott Nason, former chief information officer at American Airlines Group Inc, said long-term investments in computer technology were a tough sell when he worked there. “Most airlines were on the verge of going out of business for many years, so investment of any kind had to have short pay-back periods,” said Nason, who left American in 2009 and is now an independent consultant. The reservations systems of the biggest carriers mostly run on a specialized IBM operating system known as Transaction Processing Facility, or TPF. It was designed in the 1960s to process large numbers of transactions quickly and is still updated by IBM, which did a major rewrite of the operating system about a decade ago.
