It depends a lot on the mood of the staff on the day. In my early travel days I got away with lures and reels in my hand luggage a couple of times, then one day I got stuck, had to repack all my gear and ended up missing a flight as a result. Definitely not worth the risk, rather check in all your gear, most airlines are a lot more strict these days anyway.
That's so true. Went through the same airport 3 times on a trip in Colombia. Same luggage, same everything. 3rd time they stopped us and we had to take off all our braid of the reels. Almost missed the flight and left a few k of braid on the floor at security.
