Fortunately for me now, I no longer travel with my large format camera, (4x5)
yes I know most people probably have no idea what I am saying, but when I use to travel with it, Pelican cases were my luggage of choice, had a insurance policy that covered travel. but in the 15 years plus, never had a problem with AA on checking it in, the cases are made very well, only problem I have had is when coming back to the states, it took for ever for the pressure to release, so customs could inspect the bag
