I smoke and fly SYD AKL LAX twice a year. Not being able to smoke on a plane doesn't bother me in the least. Airside at AKL there is an outdoor smoking area - not great when i was there last time in the pouring rain and wind but, oh well......

NRT is great for smoking. ANA have a superb lounge with a separate room for smokers and not one of those silly bubble things which i refuse to use ( i would rather not smoke then sit in one of those) .
