I have mixed experiences.. Sometimes they let me bring the tripod on board, sometimes they stop me at the boarding gates and make me go all the way out to the check in counters and queue up again just to check in the tripod before allowing me to board. As you can imagine, it can be somewhat frustrating. I realise that it's more of the airport policy rather than the airline's policy or even the country's policy. Cos I've had different experience with the same airline and in the same country too, just different airports. I have experience where the airline check in counters let me through, but I was stopped by the airport's customs officers at the departure lounge.
night86mare, r yr tripods small and compact and kept out of sight in ur hand carry bag? I carry mine in my hand. I wonder would that be the determining factor?
