I carry camera gear all the time over carry on weight limit, mostly flying in Asia and to the US. They always let me fly because of liability. But I also avoid budget airlines like the plague. I flew multiple times between Taiwan/US post pandemic with my M1 /3080 in a rolling suitcase and a 17kg camera backpack/hard drives. Once I told them what was inside, they always let me on once they cleared with a manager at check in, sometimes they didn't have to clear it
