Jetstars maximum length is 2 meters for surfboards.
Lets get this policy changed.
Write / email to Jetstars customer service and request that they review this 2m limit.
They will be using wide bodied aircraft to Bali so there is no reason why they should have this restriction.
After all, where be taking big wave guns, mini mals, longboards to Bali for decades with no problems on Qantas, Australian Airlines, Garuda etc.
Lets all contact Jetstar and change this policy.
Do it.
PS I do not want to hire a board off the beach.
