bordbar are a Cologne-based company that upcycle the aircraft trolleys that cabin staff use to serve food and drinks, turning them into household furniture.
I like their flightcase aesthetic. bordbar are selling Air Berlin themed trolleys on their site and have done a number of different designs of trolleys for Lufthansa to sell via their own Worldshop. The bad news is that these are currently Germany-only. More information on bordbar here.
