I'll be traveling to east Europe and for that reason I had to switch to a small compact tripod so that I could carry it easily. The new tripod, when closed, will not exceed 43 cm and it weighs below 1.5 Kg. However, it will be attached to the side of my backpack. (This tripod cannot be converted into a monopod)
However, I'm not sure if carrying it on board would be a problem or not because I have never done that and I have always put my tripod in my luggage and checked it in. But this time I will be traveling with a backpack only as the trip is short.
The other question is that if I check in the tripod, like I put it in its own case (has no protection), would the airline take good care of it?
I called the airport police and asked them, but the said they have to see it first to confirm if it can be allowed or not.
