You're an idiot  

They have already flown passengers on autonomous aircraft. It won't take too much for people to make the switch.

All they will have to do is tout the safety record of autonomous aircraft vs piloted aircraft as 80% of accidents are human error. Then provide highly discounted flights and fill voids during the next pilot strike which will eventually come. The transition will happen. Or in the case of the military, just tell the troops to get on. Then use that record to sell it to the public. 

You will always have the early adapters and those laggards who will wait to see how it goes and may take a while to warm up to the technology, but it will happen.
