I am planning a trip from Hong Kong to New Zealand towards the end of this year and I want to bring my fly fishing rod. I am planning to purchase a tube to put my 4-piece rod inside and the tube has the following measures: 27 inch or 68cm.
My question is: Can I take the tube as carry-on rather than check it as checked luggage? I have checked Qantas, China Airlines, and Virgin Australia websites and I am informed about their travel policies (some do actually not state any information about my specific case). Hence I wonder what are the experience other travellers had most recently. I am asking about experience dating back only to 2013-2015 because obviously travel policies change.
I read that when stating that the content is "delicate,fragile, and valuable" that most airlines treat rods in such tube like music instruments and allow travellers to carry-on. My tube as stated has dimensions that should fit into every over-head compartment.
What can I do to make my case? I just feel very unsafe and uncomfortable to check in a 1000+ USD rod where the tube has to remain unlocked due to potential inspection.
I think that despite asking for experiences and knowing this is not the perfect fit for StackExchange the question still stands because ground security services and airlines most often handle issues like this on an ad-hoc basis rather than going by policy (as evidenced by the lack of information on the airline websites).
