From experience I can say the Telco industry is exactly the same.
It would not surprise me to find any industry that has been around 40+ years will be the same - they want to spend time and money doing what they do, IT is seen as nothing more than an expensive nuisance.
Love them or hate then, that's why for example Uber & Telsa are so "disruptive" - they are focusing on the IT and the "Thing" (taxis / cars) is virtually second best.
This did happen in Europe with a RyanAir and EasyJet. They used a system called OpenSkies that was far cheaper to operate. It lacked lots of the of connectivity that the old systems have to Travel Agents and other Airlines.
Those companies are "disruptive" because they keep pushing boundaries and experimenting with new ideas. They are willing to gamble and lose, or even just spend money on an experiment with no known ROI. Kinda like Bell Labs of old.
The stock market has trained the older enterprises to stick with consistent returns. Don't rock the boat, don't mess with the cash cow.
"Exactly the same" only if you ignore everything about them that isn't consumer facing. Telcos are high-profit margin regional monopolies, whereas airlines operate at the margins and are fiercely competitive. Perhaps the only thing that can be said about them being similar is that they are high barrier-to-entry industries.
