What they could do is make it so if you have your pilot license and have enough hours on that type of plane, you fly free.
If they can get one certified passenger on the plane, then it flies without a pilot and that person is put responsible in case of emergency. It could be an incentive for people who fly a lot to get their pilot license as they'd get to fly for free.
In all realisticness though, I would not think it's a good idea. Look at when something does go wrong, you need the pilot and copilot and even some more crew working on remedying the problem. Most issues with modern planes involve electronic/computer stuff. Imagine that happening to a remote controlled plane.
In theory with enough safeguards and built in emergency land programs etc it could be done, but one small mistake or bad line of code could throw the plane right off course. Ex: accidentally loading Apple maps engine into the trajectory system. Next thing you know it's trying to land upside down in the middle of the Atlantic.
