Hypothetically, How risky is taking a rabbit on a plane in cabin?

I might be going on a 2 hour flight in a week. And I got the curiousity to ask if a rabbit could go with me. But I read online some possible outcomes but you can never tilt trust the Internet. So I'm asking you guys on Y!A. Don't bash me for being curious i'm not actually takin him it was just a thought.
