Would it not be an idea to give away/sell, selling obviously having more attraction for an airline, either nicotine gum or inhalators on board? The problem is that a lot of people cannot plan ahead, personally I know i won't be able to smoke , so equip myself beforehand, but a lot of fellow SLF are a tad errrr slow. A spot of nicotine replacement at twice the market rate may help them to have an more enjoyable flight, as well as everyone else on board. May even persuade a few to give up. Although I always get a funny look at the chemists when buying the gum.
"hows it going giving up then sir?"
" err not giving up , just off to the states"
" ?????"
