Lots of research is out there to show that the optimal distance is around 3000nm. Below that the extra fuel on departures and climbs pushes the per-mile fuel burn up, above that the extra weight on board pushes the fuel burn up.

If the aim is to go from A to C then there is nothing gained from a stop at B.
It is not only time but also fuel inefficient as there is much more fuel wasted in landing, taxying, taking off and climbing to the high flight Levels than just staying there in the first place.
That flying non-stop is more expensive than with stops has everything to do with the fact that Airlines like the hub and spoke model to get higher passenger loads and that passengers like to fly direct and are willing to pay extra for the privilege rather than any extra fuel Costs.
The extra costs of having crew work longer and therefore more staff required etc would outweigh the fuel savings by a massive factor.
If people want to do something about green-house gasses they should fly less, not go on cruises, put PV panels on their roofs, eat less meat, and buy EVs.
Flying shorter routes is not the answer.
