I didn't think I dared check the spacecraft model. Despite the protective case, I doubt it would survive the jostling.
If they forced me to check, the safest option would be for a friend to come to the airport and retrieve model, leaving me to fly without it. But there now might not be enough time, as airports are never central ⏰
Could I promise the spacecraft wouldn't eat an airline meal?
Or should I promise I would eat TWO meals, to make it look like a human was in that seat?
Could I declare the model an emotional support spacecraft?
