snapware from target, I bought 2 and use 4 layers.

glues tin sheet to bottom with liquid nail.
magnetized bases.
Tall enough for a speeder on flight stand.
Taken on planes and around the U.S no issues.
Travel is easy when the only things i have to carry are this, back pack with gaming gear (which you could use an empty layer for) and a fold-able display board which fits into a layer.
Otherwise i would use a Tablewar display case. I've seen people check them in on flights with the models in foam in the case and then set them up for rapid deployment at tournies.
