thanks for the response guys, since we posted the topic, we've been looking at a number of alternative travel options. The tube we had was a manufacter's tube and we are looking at testing a couple of options - an aluminium telelscopic tube and a thicker PVC job. Certainly, if we can get them on as 'carryon' and have them stowed somewhere by a helpful cabin person that would be ideal, the other alternative is the 'rod case' we have seen on the net, made out of aircraft grade aluminium, and rectangular in shape, but it looks like you can't get much in them even if they are fairly tough. It would be good to know just how many rods they will accommodate. The little 4 peice 'poacher' setup is certainly easier travel wise but sometimes you just have to take a big two peice with you cause you can't resist Anyway, it's all a good excuse to do some more travelling and exploring more fishing.
