//Worse case scenario is she died from alcohol poisoning and that still wouldn't reflect onto the airline.//
No? Let's imagine.
--------------------------
The scene: A courtroom somewhere in the High Court. The case for compensation is being brought against EasyAir Ltd by the deceased's family for its failure to ensure the safety of one of its passengers to such a degree that it contributed to her death
M'Learned Friend, (Sir Hartley Redface, QC, for the deceased's family): "So, Ms Stewardess, you were confronted with a passenger who was so intoxicated that she was out of control and was threatening other passengers and the crew?"
Ms Stewardess: "Yes, that's right."
Sir Hartley: "So what did you do to try to calm her down?"
Ms Stewardess: "I gave her another bottle of wine."
Sir Hartley: "Why did you do that?"
Ms Stewardess: "Because it's company policy to serve people more drink when they are drunk and agitated. It's what I was trained to do."
Sir Hartley: "The Court has heard that the passenger subsequently died from alcohol poisoning. Do you think your actions and the Company's policy may have contributed to that?"
Ms Stewardess: Er...er…
Sir Hartley: No more questions, My Lord. I know it's almost half past eleven and we've all had a gruelling morning but if I could call my next witness before we retire for some well earned refreshments.
Lord Justice Cocklecarrot, QC: Oh very well, if you must.
Sir Hartley: I'm extremely grateful for your Lordship's kind indulgence. I call Mr Jason Spiv, the Chief Executive Officer of EasyAir Ltd.

People have to behave themselves when on board an aircraft. If they cannot because of fear, anxiety or just general slobbishness, then they shouldn't fly. Your suggestion that they should be served more booze in such circumstances is as incredible as my sketch, above.
