There are two sides to that coin. Taking a cigar on board is no problem. You of course cant smoke it (FAR) but taking it on board isnt a problem. But, say you were trying to get a smoke across a border... The I would recommend putting it in your bag. Example.. In mexico, you have random searched.. there is this little traffic light, you push the button (or try to miss it) and if it is green you go, if it is red you stop and get searched... now them finding cigars on you isnt bad, but when you have bands attached to them that arnt legal, it presents a problem.. if your taking them with you, remove the bands, hide them in your luggage, or throw them away.. (Your going to be smoking it anyway.. right?)... say it is a native smoke that is eligable for exportation.. Sure helped me get some great Mexican smokes.... Also, some places will even reband your cigars for you.. this is not legal, and I would question any sellers ethics that did so...
