Stephen Amell is expressing regret for the behavior that got him kicked off a Delta flight in June after a disagreement with his wife, Cassandra Jean. The _Arrow_ alum, 40, addressed the

incident during an episode of Michael Rosenbaum's podcast _Inside of You_, admitting that he feels "deeply ashamed" about his past actions. "What happened was — and
