"Not until they invent planes that you only fuel up once and never pay for fuel again."
Sorry, I was not clear.
The single payment I was talking about was the purchase cost of the robot. Beyond X number of flights the saving from not paying for pilot (or co-pilot) pays for the 'bot.
If it's also lighter than the average pilot that can also save a (smallish) number of Kg of fuel per flight, but over the life of the aircraft that can also be substantial. Otherwise they might trade if for something else. It might put new routes within range of existing aircraft for example.
