The pic and pluck foam looks nice, but it takes up WAY too much space. If you are like me and you pack these puppies to within an inch of their lives, you want the dividers. That being said, I bring two on the plane with me (one for me and one for my wife) and have never had to check them. I assume that they would survive checking, but I would prefer not finding out. Much as I love my 1510 Pelican cases, they are HEAVY. They weight almost 15 lbs with nothing in them, which exceeds the weight limit of some airline carry-on specs. I have never been challenged, but I that the way airlines are going these days, it is just a matter of time. I have been thinking of replacing them with something lighter.
