Theories abound around how to get your suitcase on the carousel first. But what do the pros say? One baggage handler writes on Reddit that the key is being one of the last to check your luggage in. "Show up mostly late, but not at the last second. Your bag will be stacked on top of the cart, be the first loaded on the plane, be the last loaded off, and the first onto the carousel. It’s probably 70-80% effective." Another handler adds that weight and size play a part in determining when and where bags are loaded and unloaded. "Timing can help," he writes, "but size, shape and weight also come in. If your bag weighs 80lbs (36kg), it's going on the bottom if we can help it."
