Last time I went through cabo they made me check a fishing rod in checked baggage (instead of carry on- it was very small), but I don't remember if the fishing reels had to be in checked bags. If so, I won't bring high end spinners.
A little trick I’ve used in the US but may work elsewhere. Put your rod tube in a ski bag, you know, a bag you would carry snow skis in and check them. I never got asked and they seem to be more careful with skis. This was a decade and a bit ago but it worked fine back then. YMMV
