When asked at check-in "what's in the bag", say fishing rods. It should go hassle free.
In case you're wondering, yes they do make and sell fishing rod cases as long as our paddles. I almost found a real fishing rod hard case to do the job, but width was just a little shy for the blade.
How do I get it? I made it myself. I learned to sew repairing kites.
My next surf trip I'm taking my paddle and renting a board.
