Baggage. Even if you think you checked it all in the terminal, you're bringing some on board with you. Baggage. Everyone's got some and in the confines of an aircraft it surrounds us and mingles together. Is this your bag or mine? Is there a better metaphorical juxtaposition in air travel than "baggage carousel" where your personal baggage gets to ride the horsies?
In this playset by Fiasco-veteran and writer Will Hindmarch, the airplane serves as a pressure cooker where all the passengers stories are mixed together and set to a boil. You should probably buckle up, don't you think?
