The last time I flew alaska airlines it was 8 foot, I know you can pay more for a longer rod but I'm not sure how much more they get you for oversized cargo , look it up on the web on the carrier you're flying
Flew where with Alaska; their policy is 115" OAL for the case, I brought my 9'2 popping rod to PV no sweat. There are some airlines that will let you bring 10' longboards over but it's not cheap, I imagine a 10' today is going to be a pain too.
go make friends with a local , and have them take you. it's a very specialized type of fishing. I caught my first in maui, only after making local friends and using their stuff. the rods were custom and 12' long. we used slide hook/baits, and break away grapnel sinkers. we caught little bait fishs in the tide pools , and had a little blow up kids pool that we filled with water and kept them in it. we fished an out going tide. first time I tried this way I got my first @108lbs. man what a battle.
