It seems every time I go abroad the different airlines, at each end, enforce their rules more or less harshly randomly. You may get to where you are going with no problem, but may have someone a bit stricter coming back.
I was away last week with Jet2, and while I had no problems, coming back they made a point of getting the metal frame out that they use to check bag dimensions prominently, and they do this at the gate, not when you check in, giving you less time to change anything not within the rules. And there is obviously time constraints at that point which may force you just to habd over any cash they are asking for. :bang:
I didn't see them checking anybody though. I did see them telling a few women to put their handbags into the other carry on luggage they had, as it was classed as another hand luggage item. If the tripod is not in a bag, or by being attached to the outside makes the bag too large, then you may have problems. :shrug:
I always put my tripod in the case the goes in the hold of the plane, and had to find a tripod that fit in my case. All the other camera gear goes on the plane with me.
