yip, I'd go along with the previous comments here..
any sharp objects like hooks etc will not be allowed to be carried on to the plane in hand luggage, but they can be put into your main suitcase and checked through. Most things can be put into your main checked-in luggage, even fishing knives.
Fishing reels and line were ok as hand luggage (nice to have them on your person if they are valuable and have sentimental value..
) with the last airline that I travelled with but each airline could all have their own separate polices, worth telephoning them to check if need be.
however, i have had a telescopic rod taken from me on one airline. My impression was that fishing rods were seen as over-sized for hand luggage (they wouldn't fit into the overhead compartment) and so I thought that I would be fine with a telescopic rod that actually fitted into the hand luggage (i should have been?!). But I wasn't, the guy wouldn't see the sense of it, the rule was no fishing rods as far as he was concerned, period.
Stick your telescopic rod into your checked-in main luggage or buy one over there. Rods aren't particularly expensive to be honest, cheap combo packs can suffice in many occasions, sometimes your can even hire a rod for a day or two. Otherwise, if you really want to bring your own good rods, then you will have to purchase a rod carrying case and pay for the excess over-sized luggage.. maybe £30 each way.
Good advice about just buying your terminal tackle over there as you might see different tackle (hook sizes etc) or better unexpected tactics for the different species..
I'd personally just bring a good reel and line and then put a telescopic rod and some tackle into the check-in case.
