I am by no means an industry insider, but I’m skeptical of your claims about running a ln airline on tech from those eras. The visible side of airline IT (ticketing) perhaps, but surely there is a lot of behind the scenes software that facilitates the efficiency of operation (plane positioning, route planning, maintenance tracking) required to compete on price in the modern era.

It’s easy to complain about modern airlines (and I do), but it’s still true that’s never been cheaper to fly, and IT infrastructure is surely no small part of that.

I think the ticketing systems are probably the most modern parts of airlines. As far as I know, the tech that actually runs the plane does not change very often as it needs to go through approval processes.

The ticketing system might very well be the oldest.

AFAIK the very first large-scale commercial deployment of what we now call "distributed cloud apps" was SABRE, a ticket reservation system built back in 1960s, still in use today.
