On international travel ... i travel throughout the Pacific rim.
Any roll-on that works in the US will work out in the system.
If you are talking about true storage in an unit off site from your house, then a pelican is the choice. there are a couple of other options out there but they all look/work like pelican.
Personally, if i was a full time shooter with most of my work require traveling on a plane somewhere - particularly flying over the pond (east or west) ... i would go to a hard case pelican. Especially if you are going to beaches and other non concrete locations.
