Recently there was a news story about a passenger who urinated on a fellow passenger (https://www.flyertalk.com/articles/p...-over-him.html) and the comments section was rather unsympathetic to the victim.

So this made me curious about what, if any, legal or contractual obligations airlines have regarding passengers' interactions. In most jurisdictions urinating on a person is regarded as a form of assault, so then does an airline's legal immunity extend to other forms of assault. too? For example, over the years there have been various news reports of passengers punching other passengers, and of women being sexually harassed or assaulted by male seatmates.

So in legal or contractual terms is the airline regarded as an un-involved third-party and the dispute is purely between the pax in question? If a passenger wanted to bring a legal action against his or her assailant is the airline obligated to provide address and identity information about the other passenger so such a lawsuit or charges can be brought? I travel internationally quite often so my seatmates may often be from other countries or continents than me. If such an event occurs in international airspace whose laws or jurisdictions apply?
