Good to know. I've flown down to Costa Rica three times with a kayak using American and have always had to wrap the boat in packing plastic and lie to the baggage check-in lady saying my kayak was a kite board. I figured if I didn't know what the heck a kite board, some lady at baggage check-in wouldn't either. I was right until the last one. She busted me, told me she knew it was a kayak, I denied it, she let me on anyway saying, "I still know it's a kayak."
I figured my days of taking kayaks to C.R. were over, but GOD BLESS FRONTIER! They must be the only airline in the world that has figured out that playboats are about 2 feet shorter than the average surfboard and not much heavier.
