Those used to exist, nobody flew on them and they went bankrupt. The market has decisively decided. In airlines, price beats all else, even time in most cases.

My read of TFA is that they also aren't keen to compete on price.

I don't think this is unilaterally true. Alaska Air is has remained consistently pretty good in my experience, even through the Hawaiian Merger.

"What if the airlines instead focused on delivering great service at a competitive price?"

Germania tried that in the late 90s, offering a flat fare for every seat.

They had to roll it back within a few weeks because their bookings dropped unsustainably - nobody wanted to pay a fair price for a seat, even if it was cheaper than they might have had to pay under dynamic pricing. All that potential customers fixated on was that the flat fares were more expensive than a few limited cheap seats on rival airlines.

The market can remain irrational linger than you can remain solvent etc etc
