MZFW,
It's not just the charter companies who need to do something (unless the scheduled carriers have something subtly different about their aircraft and holds etc!)
My recent flights have included:
BA and GF out of Saudi and Bahrain to UK,
US and AA out of UK to USA,
BA domestic (well, to the Independant State of Scotland to be accurate!)
SQ between Gulf and Dununda
SV domestic & "Gulf local" sectors
QF and Ansett domestic
UA from Dununda to USA
US domestic USA & Canada
- a total of maybe 50-60 sectors in the last 12 months
Not one of these flights as had clear notices at check-in (unless I missed the small print) and none had any PA about "throwaway" lighters (although by that time it would be a bit late for checked baggage!)
Now in future, I'm gonna have one, and only one, in my pocket - but how many of my fellow pax, especially travelling from the Gulf to UK where the price ratio on these is 2 or 3 to 1, and who sometimes have 4 or even 5 weeks holiday and so "stock up" before leaving, are gonna have 3 "spares" for themselves and 10 more to give to their mates in the pub back home, all stowed in the suitcase in the hold
