Bane hated planes more than he did driving, but flights meant that he could get from point a to point b in less time by flying than he ever could driving. Plus there were some nice things about flying that made it worth it for him on certain occasions.
For one he could sleep when he was too tired to work. Two, there were always decent drinks that he could have not to mention entertainment as well. The third was that he had time to collect his thoughts without worrying about what those around him thought.
The alpha hardly ever traveled with anyone he knew by plane. Having strangers around him meant that he didn't have to worry about what anyone else would say or think about him. He would be having to deal with them briefly before never having to see them again.
