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.
