Taking your board?

So... Ending September start of October my dad and I will be going to Costa Rica. Jaco or Playa Hermosa. We've been once to Jaco but not exactly for surfing (it was though the first time I tried to surf and got wiped out nicely). So, my question is... How reliable is it to take your own board on an airplane? I wanted to take my Flyer 6'6" or do you think I should simply rent one out there?
