Wings Air charges 100 bucks per surfboard, so just had to pay 300 bucks for 3 boards on top of the 450 for the flight. 750 AuD for a 1,5h flight??? Smells like BS. If you have more boards in one bag just lie about the amount, its gonna safe you a lot of money. If you are looking to travel from Bali to sumbawa, just rent a scooter there and take the two slow ferries, crossing Lombok. Might take a day or two but it should safe you a fair bit of money, peace out ✌️…
