There is another interesting way of thinking about this. They might be more inclined to use air travel than road because the 'element of control' is lost from them in both modes of travel.

My car is much nicer than any seat in coach. I won't be touching or smelling the people around me. Nobody will screech "safety information" at me and then provide desultory food and drink service. The sandwich from Rein's will be tasty, and I can reek of garlicy pickles without offending anyone. I'll watch a movie from the Millennium trilogy in the extended cut with the profanity and nudity, and I'll talk on the phone as loudly as I please.
Once self driving cars come, airlines will rediscover service and make 80% of their customers pre-checked or they will lose half their business.
Going strictly by time to reach destination, people will consider "time from when I want to leave my house" or "time before I want to arrive that I need to leave my house".
In many cases over land, they'll find that an autonomous car will be faster.
