I reported the problem to the flight attendants in all three flights as soon as I smelled the cig smoke in the cabin and each acted as if they were investigating the problem by going and sniffing around the bathroom where the passenger presumably smoked but then they didn't take any further action such as making an additional announcement to remind passengers not to smoke in flight and didn't make an effort to alert the Captain. It is dangerous and unhealthy for other passengers for there to be open flames and bad air on the flight. Why is it tacitly condoned by flight crew?

In one instance, the 2nd time I reported it on Sunday night to a 2nd flight attendant since it was the 2nd time on that flight that someone was smoking, she told me she didn't smell it! All the passengers around me in mid cabin smelled it. I think this makes for a very very negative customer experience to be trapped in a medal tube filled with cigarette smoke recirculating throughout the cabin and a flight crew that doesn't really care.

Please fix it and make it so the smoke detector can't be tampered and that passengers face stiff penalties if they choose to smoke on board. I'd be interested to see if other customers have similar experiences and what solutions AirAsia thinks can be implemented.
