And be glad you're not a professional surfer.
"It's mind-blowing how expensive it is to travel with surfboards," said Hawaiian pro surfer Fred Patacchia Jr. "I just recently went to Europe on American Airlines and was charged $150 per board, traveling with nine boards. You do the math. The surfboard charge was more than my ticket cost."
Delta, he added, charged him $200 a board for a flight in October from Hawaii to Puerto Rico, when he checked three boards.
Airlines say they charge service fees for surfboards because they require special handling.
"They tend to be much larger items and are somewhat oddly shaped, which makes it more work to fit them into the belly of aircraft among standard baggage items," said Tim Smith, an American Airlines spokesman.
Cynthia Tinsley-Douglas, spokeswoman for AirTran, said her airline charges $79 each way for surfboards and bicycles because "both items are more cumbersome and fragile than other types of sporting equipment."
Surfboards can get big, to be sure. Longboards, which may run 9 feet or more, won't fly with many carriers. But popular shortboards, commonly around 6 feet long, fall within the usual size limits for checked sports equipment. Although wider, they're about the same length as alpine skis, which many airlines fly for free. Go figure.
What to do? Consider renting a board at your destination; prices vary a lot, but about $30 a day is common.
Or ship your board with a carrier such as FedEx or UPS. Depending on the details and destination, you may or may not save money, and you'll need to arrange drop-off and pick-up of your board for shipping.
Or do what Hawaiian pro surfer Bethany Hamilton does. Hamilton, who said she recently spent more than $1,000 to check four boards from Hawaii to Indonesia, seeks out what she calls "surfer-friendly airlines."
