To check a surfboard at the airport, you will need to take it to the baggage check-in area. The process is similar to checking any other type of baggage.
You will need to present your boarding pass and ID and the surfboard will need to be properly labeled with your name, address and phone number.
The surfboard will then go through the X-ray machine and you will be given a baggage tag to attach to the surfboard.
You will need to keep this tag with you, as it will be used to claim your surfboard when you arrive at your destination.
