Transport of the Minis by Plane

Hi all =)

I'm wasting my time atm by checking the diffrent possibilities, how to transport my Deamonarmy to Serbia by plane.

Does anyone have an advice, whats the best transportback or something? Since the Deamons have a few quite... "big" Modells (like the Drohnes, or the Canon), it's not that easy to finde something... I'm thinking about making a "suitcase" filled with stealplates, where the figures are fixed per magnets, but in the end it should fit into the handluggage of the plane (max. 55x40x23)...

So yeah, any ideas?
