I've been flying with my tripod checked in a medium sized Tenba TTP case for a few years now. I always pack the tripod with the head attached, but the handles removed or loose and never have had any problem, but yesterday it really passed the test.
My connecting flight from Phoenix to NYC was delayed, so they announced they would be doing a "quick turn" to get the plane out as soon as it arrived, and in rush mode I watched the baggage truck make a turn that was a bit too quick, sending my tripod case flying from the top of the stack onto the tarmac, followed by seven or eight other suitcases. I had my Tiltall in there, Minolta Flashmeter III and accessories, Linhof 6x7 back, small Metz flash unit, flash bracket, and a few other odds and ends. All came through unharmed.
